Where would Arc GL be for example with the scaling removed. His passive and ult as the only way to "improve" with utility?
They are in the upper right section, so I guess you could try making them more bursty late game, but doesn't that end up with the same issues as zatanna and harley are at right now, in which they are venturing too far into the other hexes?
Maybe improving the ratios gained from Eye of Ekron and Deadshots would help, but I don't see the end goal with Controllers, which I've kinda wondered for a while now. If giving great CC for a huge item investment isn't in line with the utility goal of the class...what is? It can't be just shield or heal boosts.
