Mage's options on the new keystones seem a bit weak?

I mean compared to what adc's have, the option that mages have look a bit lackluster. Adc can pick between wanting to pick more atk speed, more dmg on the same target and ofc warlords bloodlust junior. Mages have Summon Aerie works only on some mages, arcane comet is a pretty decent choice and phase rush is kinda niche. I mean why mages dont get something to amplify their dmg. Not all mages want to reposition themselves constantly, and sure as fk not every mage has shield. Some just want to deal dmg.

Hell even number wise keystone for mages are kinda weak. Comet has 100 base dmg at max lvl and the scaling sucks ass. And no, gathering storm needs to be heavy late and EVEN THEN the numbers that it provides are flat, compared to the adc's which are %.
