Is there any in deep explanation of stats in this game I could read? For example how damage is calculated exactly and how Potential affects stuff.
Yeah, it is broken indeed (but in a good way). I'm level 28 and I'm already chaining Overdrive 5 or 6 times, but it's quite risky to do so at this point of the game.Example of an infinite overdrive build

QisTopTier has a great support build and his beam did 40k damage, but with an overdrive set up you can keep it going forever and consistently rack 20k per art with very little cool down times at all.
This is lower level, the damage you do gets ridiculously insane later one.
You eventually get into the 300,000s and if you're really crazy millions since it's infinite. And you don't need to worry about dying at all because Ghost Walker is GOAT support ability.
There are tons of different examples and builds, this is just to show how broken Overdrive is.
