the fact is, some champions need nerfs SPECIFICALLY for dominion. Darius, Jayce, and Kassadin to name a few. Darius needs to have his ult not reset on kills in Dom, it's just way too broken to be able to kill and entire team. Remove like, 2/3-3/4 of the CD on kills. Jayce needs to just be all around nerfed because he's too good in too many ways(self movespeed buff, team movespeed buff, amazing poke, CC, steroids out the ass, etcetc.) Kassadin needs a longer CD on his ult, about 5 seconds at all ranks would be acceptable. Tweaking his other stats to compensate for the longer ult CD would be acceptable.
