As lancer main, if you wanna give mages 20 skills instead of 15...
I'd be ok with that. Right now they seem to be lacking a lot and this is 50 levels we're talking about. Go ahead and give mages more, its ok with me. Its sad to see an entire elemental nuke be left out and debuffs.
As a player of a different class, I would not be jealous at all and think they should probably be included.
Btw I'm refering to the upcoming patch where a lot of things are changing for classes and we're all being downgraded to set numbers of abilities an how many things we can cross class.
