Evelynn Ravage change is interesting but doesn't address her core issue.
Evelynn has a ton of problems, but there are a few that stick out the most.
Ultimate: Works on current damage, it cannot kill, the shield is rather weak and synergizes only if she builds tanky. It causes confusio for her identity. Hate spike: Perhaps a lowering of mana cost, sustain on large monsters, or normalization of her AP/AD ratio so she has a little bit more early game damage? Ravage: The on hit proc idea is nice but ultimately, the issue is that Ravage being physical damage causes itemization problems that are far too much of a headache.
It was stated that if evelynn wants to deal damage she needs to build it, but Ravage being physical means she suffers a penalty for it. BUild AP for burst? You have no armor pen. Build AD to get armor pen? You're missing out on burst damage. Could it be considered for it to have it returned to magical so itemization is not as problematic? After all, DFG is being removed, her ultimate deals current health (so it cannot kill anything), and the base damage on ravage was lowered. Turning it to magical wouldn't be an extreme buff, and it would be a slow change.
