I've played 5 characters so far ranging from full on melee, to stealth, to magic. In vanilla, stealth characters were the weakest but only just and only due to underpowered (or over balanced) missile damage. (An arrow damage mod like the one i use changes that dramatically.) The second weakest was the full on melee character who, with the aid of Bethesda's level scaling, only found the battles getting longer and harder as he progressed. The most powerful, by far, was the Atronach ensigned sorceror that i made who relied solely on his destruction and blocking skills in combat. None of that running backwards and casting BS. In fact, he didn't run at all. Ever. If one has the right spells and knows when to use them, one needs only walk towards the enemy...
Thanks for the arrow stats. The mod has indeed changed them. As for the use the glass/sell the ebony thing, you'll find that as your missile weapon skill progresses, the difference between the two will become more apparent. Hold onto 'em and use them for those special targets.
