That would be way too complex and hard to balance out. My idea is to increase effectiveness without changing much more than that. Early effectiveness would be about the same but per level gains would be reduced so lets toss this idea at Nunu's Blood Boil.

currently 25/35/45/55/65% attackspeed with my change it would be reduced to 20/25/30/35/40% attackspeed but Utility power would based on my rules for utility power increase this buff by 1% per 1 Utility power you have. getting over 100 Utility power would be hard to get and I already have some pretty good rules in place to balance out its interaction with numerous type of Utility.

Anyway back on topic with 50 Utility power the attackspeed buff would go from 20/25/30/35/40% to 30/37.5/45/52.5/60% and at 100 UP it would be 40/50/60/70/80% attackspeed.

I'll list additional rules for UT scaling later Slows, hard CC, and debuffs have a really strict UP scaling and cap.
