As an erebus player (currently), I'd like to argue he needs his bite back, but the reality is I agree the nerf puts him in line with the other demigods...
WITH ONE CAVEAT....
Bite NEEDS to get fixed, particularly after bat swarm. After bat swarm is generally a very critical time for erebus. Since your goal was probably to catch a demi off guard, he's probably going to start running for towers, or even already be behind towers. You need that bite for two reasons: To slow him down to ensure you can keep hitting him (and so when he dies you're closer to the tower wall exit) AND for the health to continue staying behind enemy lines despite the towers. If I die because I didn't have mana for the bite or I died despite the bite, that's my own stupidity. When I die because bite never fired from this stupid bug, I don't consider that my fault. If the "bite not firing" bug is fixed, I'll be pretty happy with where erebus stands atm.
