Ok so the game doesn't use a use-based system, despite seemgly trying to trick you into thinking it does. It's all based on whats "equipped" (slotted on hotbars, on equiped on char)
My question is does it matter if you multiple skills from 1 tree for leveling it's main skill line? Does it get more xp with more slotted on the hotbar?
You'd think it would.. But my limited tested showed no... I tried two handed vs aedric spear, and one leveled faster then the other regardless of how many I slotted for each (as long as I had 1 of each). I tested it a few times and it was consistant, but maybe there was another factor throwing it off.
Can even slot things you cant use and level them. (EG: sword and board skill while only using a two hander)
