New Xerath Passive Concept
#EDIT: Ight nvm you guys are right that Xerath needs to AA for balancing purposes. I still like my idea but I get my concept isn't balanced.
#Mana Surge
##Every 20-12(based on level) seconds, when Xerath hits an ability he will regenerate 8-22(based on level) (+8% Ability Power) mana over 3 seconds. The remaining cooldown can be reduced by half once if Xerath hits another ability.
Frfr Xerath's passive feels like something that was just slapped on him to help with mana sustain in lane but it doesn't really feel part of his character. Xerath is suppose to be an ascended but not where he takes the form of an animal but pure arcane energy that had to be contained in a magical sarcophagus.
This new passive will still serve the same purpose but reward the player for actually hitting their skillshots and help Xerath to dish out more spells without going OOM.
It would have more of that feel of a Supreme Magus who is control of the arcane to its full extent.
##Take it or leave it just getting my idea out there. All numbers are obviously flexible for balancing reasons.
