Well I started the game a few days after the OBT. I had played the game in CBT up to level 20. So I didn't really test the game fully, so I tried the game again hoping to see if the game was really all, up to the standards people were saying.
There are 5 classes in the game which are: Bezerker(str based), Champinon(vit based), Heretic(spr based), Magus(int based), and Slayer(dex based). I chose to play Slayer since I liked the whip like weapon it had when creating the character, and I am basically a kill everything fast type of guy.
At the beginning of the game we start is Expedition Camp, there is a sort intro tutorial were it tells the player what each button does as players play the game. There are plenty of quests to do, and all which gives players gear for their character, gear is given through out the game as people near their equipment level, 15, 30, 45, 60, basically every 15 levels. Note that normal monsters do not drop gear, only bosses. Once the player reaches level 20, they will enter Atlantis, the main city where all players can heal, buy equipment and even do events.
The game gives tons of quests which players can solo, giving them about 5% of the exp for their level. There are also Events, held daily, some which can be done everyday and some for each day of the week. Each event gives out massive EXP, and then some give out EXP and Items. Most of the special items can be obtained only through a Event. Because of these special items, most of the Events require full parties which are sometimes hard to find.
Since I played Slayer I find it okay to quest grind on my own, I found myself being mobbed a lot which took my hp down a lot, but it wasn't anything impossible, the hard part came when doing Events, where there wasn't a Champion tanking mobs, or a Heretic to heal everyone. What I found imbalanced in the game was that my class, Slayer though being a dex based class, was getting hit lots of times about 80% of the time, and missing about 30% of the time. Each class also has about 15 skills total, most which players will not use or upgrade, there will probably be about 5 active skills that a player will use through out the game. The skills that players will upgrade will cost a lot of coins(game currency) and a lot of EXP.
Before the OBT, there was a video released from a producer, saying how they took the Chinese BoI, and changed it for American users. Taking most of the cash items, and placing it as drops in the game. so that players would not have to pay for cash items.
Here comes in the mount and pet system. At level 25 players are able to get a default mount for their class, and to fortify them they needed a Common Mount Gem, some are given as party of storyline, events and then cash shop(Marketplace). The fortifying rate at each grade is, 80%,50%,20%,8%, the grade of the mount drops by 1 each time it fails. I personally spent 200 zen, just to get grade 3, that is $2 it might not seem like much, but if I failed plenty of more times it would stack up. As for the pet system this is were my real concern for the game lies. Most of the game monsters can be tamed as pets, except some bosses and event monsters. Each pet has a Quality, common, great, amazing, super, perfect, which affects the pets stat increase., then there is also the Emotion of the pet, which gives it a passive bonus, such as faster attack, more strength, vitality and so forth. These 2 things cannot be changed, unless using a Rebrith gem, which costs 30 zen or 50 zen. Next there is also Growth rate, which basically determines how much each of the pets stats gives. Lets say having 1000 growth, gives 1 strength, 1 damage increase, with 2000 growth, it will give 1 strength, 2 damage increase. This can be increased through using 1 pet to boost the other, or using an item which can be obtained from a event called Dragon Island. The growth increase is not great, and the there is a chance of failure as well as a fee. The pet system for the game also allows your pet to have skills, up to 6 skills, which can have, Attack, passive, special, blessing, support, and fortify skills attached to them. All pets have a default of 1 slot which is unsealed. To unseal the rest, players must purchase a item called Seal Removal Stone, which costs 30 zen each, what is not written in the game is that this process, can fail. I tried this 8 times, and only removed 2 seals, that is $3.60. The game sells basic skills for about 6k-20k coins, which is a lot for players 1-30. The other skills are all cash item, they are basically more powerful and include AoE skills. The only other way to obtain Aoe Skills are from Rainbow Sonata, a event held on Saturdays only. They other skills in the Marketplace cost 200 - 1500 zen, multiply that by 6, and that is $12-$90 just for pet skills(ouch!). Players can also fortify their pets, improving their attack, magic, hp, and such, their are all increase by a certain % for each fortification level. In the game you get 2 Basic Pet Gem, which lets players fortify their pet, the rest has to be bought, these gems cost 10 zen each. Note that fortification fails and when it fails, the level drops by 2.
In conclusion, the game is still not perfect; during events each class has a purpose, in solo grinding all classes are pretty much on their own and yield very little exp, exp is gained purely from quests and events. There is a Party Center where players can look for party members, but even though its there, hardly anyone uses it, and resorts to world char(/w). The game lacks skills, every class will basically be following the same skill build, and there is very few AoE skills. Most skills only have a damage modifier of 80% - 180%. The graphics aren't all that great, and there are some glitches. Finally, the pet system will be very costly, real cash wise, as well as having very low sucess. Though if players spend a lot of money on their pet, they could get a real kick ass pet that will drop monsters and players in no time.
Overall I recommend this game for players who like, questing for exp and doing events for items and exp, very few skills for classes, grinding on monsters, and who would like to spend a ton on money making the strongest pet in the game.
