Yeah. 8th is nowhere near as bloated as 7th was. Also, 7th was full of re-rolls as well.
I think overall, there are way less instances of things granting full re-rolls in 8th.
Just happens, that there are a few characters which grant full re-rolls, which everyone uses.
I've not played an apocalypse game since 5th edition. 40k is basically apocalypse already.
I am hearing rumours though, that units with a power level greater than 30 or 31 will only be usable in apocalypse, which would be a phenomenal change to the game.
