Mobile Champions should deal at least 20-40% less damage in their full combo than Immobile Champions
Mobility is a huge power increase and honestly mobile champions don't pay for that power increase by losing actual potential damage
They should lose a lot of damage by becoming super mobile
should ALWAYS deal WAYYYYY more damage than
should honestly out damage and out tank
in every possible scenario
should bring more to a team than 
in every scenario and team comp
Mobility creep is fine if they actually pay for that mobility in some way
Why?
Mobility is not only power its utility Its indirect tankiness Its so useful in literally every capacity Mobility champions can also deal damage far more often than immobile which alone spikes up their potential combo
And she won't kill you XD

has almost the exact same damage values as Ori and brings just as much if not more utility than Ori does.
Would see a lot more play. But as it is,
