Every new spell rework Omni gets, his core role weakens. You would think with this new 3rd ability he would become more core like, but sadly with his new 2nd skill, his core role is now ridiculously weak vs most supports. Since he has no way of dealing with disables anymore, because it's only a counter spell.
On top of that, his 3rd skill gains dmg based off his Str, which is mediocre and item options aren't the best for Omni. That said, his 2nd skill is designed to buff up his 3rd skill, but seeing how you want to save it to counter, it's really weird during fights… especially for it's range.
I realize his win rate is still over 50%; not by much, but it's due to the support role. That said, I wanted to hear what you guys thought about him now.
Also, here's a simple suggestion to make his 2nd skill work better as a core.
- Heavenly Grace: Bonus effects doubled when casting on himself.
Why this suggestion? Well currently he only debuffs his target, which you want to cast on allies. This tweak helps the core Omni out more.
