This. I could be at 100% then suddenly I'm at 40% because of their bullshit damage range. It wouldn't be so bad if their rockets weren't homing every other time. Basically Revenant + No Armor = Death
Another problem with Revenants is that while they can beat the crap out of you most of the time they have very poor health for a higher tier enemy. This can lead to people throwing hordes of them into maps, underestimating their ability to put the hurt on the player.
And their like the only enemy who's sprite doesn't match the space they take up. What's up with that?
