Stop asking GD for game design input
These are the same idiots who voted to keep flash, and look at what that decision for your game has done today. Zileas even swallowed his pride and admitted that Dota does it better and suggested something involving actual gameplay with blink dagger, but you listened to the idiotic masses.

The vast majority of GD is sub silver and does not understand game design. If you made a summoner spell called death laser that did 2k damage at level 18, these people would gobble it up. Adding another redundant layer of "gameplay" but excused under the insane reasoning of "if I can have it, you can have it too! It's balanced!1111"
