Yes, that is true, RavenX. But you are forgetting that there are also many, many traits that give you spells. These are very important. I see only three or four melee abilities, but there are I think more than a hundred spells.
Certainly we can go on and on about how spell gameplay differs from melee. That isn't really the point. The point that is important, in my opinion, is their relative strength in game. And currently, melee in the early and mid game outshines spellcasting through pure force, while also having the best survivability and requiring no mana. Once you get level 4 and 5 spells, the table tilts - melee champions are still extremely powerful, but the high-level spells are just as formidable.
In short, what I'm looking for is a nerf to champion melee strength in early game.
Edit: Sorry, I'm in the wrong topic, I thought I was in the "champion is op" topic.
Spellcasters unlock more powerful spells through traits, while melee unlock stats mostly. It seems to make sense to me.
