I don't really want it all. It's fine as it is.
I would just prefer it, as i said, if heavy armor was incorporated into the tree, even if it meant tweaking some numbers down, something you said you wouldn't like.
As for ranged, with all the abilities focused on defense and KE abilities as well, how much room are you going to have for ranged spells? Maybe one cc? Maybe an aoe nuke? I don't think more. And even then, i doubt it.
Warriors can go away from something with charge, roll, and they of course have hook to diminish range. They are not that behind in cc either, barring fear, which means less defense.
You don't really have that much advantage, but i can certainly understand keeping a line.
Now, we know that heavy armor is there, i'm just afraid i won't be able to run around in it for a long time and really enjoy it. This, of course can be just my fears.
We do know we can craft plate looking armor for both Mages and Rogues, with light materials, they have less armor obviously but it's ok. It's aesthetics i want mostly.
And yeah, around mid-game, i would expect that if i sacrifice some resources and perks, i will be able to craft heavier armor, real one.
They did show a Mage in plate in some previous videos, so there's that 
P.S. Yeah Champions should be more tanky than KEs.
