It was a bit of a painful nerf, but I think I'll live. Only problem is that it scales even worse then it did before. Although, being Erebus, you don't want long games in the first place.
To nerf it anymore would be way too much. Personally, I think that it was a bit much, but I can't do anything about that. At least people won't complain as much about it being OP.
Had two games since the nerf, lost one, won the other. The first match was lost because my ally was an imbecile who is too dumb to buy flag locks(seriously, if the game is anything but Fortress, you sure as hell better buy flag locks. I don't care if you don't have room for your shitty heart of life. Flag locks win games, HoL doesn't), and really had nothing to do with bite's debuff. The second match which was one ended up being similar... except having a good ally. Although the glitch Where Erebus stands still twiddling his thumbs when you select bite is still there. That glitch got me killed.
Basicly, I see it as this: If you played a good Erebus before, you'll still play a good Erebus now. If you played a crappy Erebus then, you'll be even worse now.
