Will combat system allow magic one hand and melee on another? Something like healing with the left hand while sword on right? I read that there will be an R button for potions or whatnot, so if that's the case, will we still be able to use at least other types of spells such as destruction spells? It would really svck if TESO will just follow every other mmos where you're limited to your class's ability only... Would make my enthusiasm go from 10 to 5.

Sorry if this was already posted, I did search but wouldn't find what I was looking for.

there hasnt been enough information on classes yet to give a definitive answer. but, yes you will be able to use magic and melee weapons. wether or not those will be tied to your left and right hands like in skyrim is not known. we do know that your left and right mouse buttons will be used for your weapons main attack and block. how that changes if you are a mage-type class is still unknown. and wether or not you will be able to bind the spells/skills of your choice to the mouse is not known. but there most certainly will be classes in the game that use both melee weapons and magic.
