Paladins is certainly a game you should look out for. Any time a game is free and it's similar to another game. In this case, Overwatch is the game Paladins is like. However, customization makes the game a bit ahead on head to head play. You can make builds and have fun being different.
Ability to make dedicated builds (Awesome)
Fun Hero classes
Gunplay seems tight
Cash shop is done correctly
Needs more heroes
Forever stuck in Overwatches shadow
PVE mode is horrible do not go in there
Needs more modes to round out gameplay
For a free game you can't go wrong. It has everything you need for pvp gameplay. And it's easy to build up in-game currency to get whatever you want in the game. So you can have a casual time and be out.
