Leave Paladins for Overwatch?

Overwatch is a much better game IMO, so if you're looking to move from Paladins which is basically just a carbon copy of Overwatch, you'll fit right in.
There are a lot more people who play Paladins, because it's free, but because of that, there's also a ton more hackers... At least in Overwatch, if you want to hack then you have to fork out hundreds of dollars, so there's far fewer of them around ;D
