I've never played Eve in her current form so I don't know how damage compares, but it certainly isn't lacking. She isn't useless. That ulti hits everyone for percent health damage with no reduction per champ hit. Everyone takes the same damage before MR. It's also in a fairly large area so you should hit at least 3 people in a team fight. Her speed boost is one of the best on a jungler at just rank 1. Ravage's AS boost is fantastic for taking down structures since it procs off minions too. New hate spike hurts and it hits multiple targets in a line.
Lastly, try walking through wards, CV, and minions on every other jungler in the game and tell me if you stay invisible and undetected by the enemy. Should go over well.
