I am sorry no one has taken a moment yet to respond to your post. I for one agree with you 100%. Do we NEED it, no. HOWEVER, this is Elder Scrolls, and that style should be an option. For example, I HATE the greatswords in ESO. I wanted a two handed sword that was not so massive for my ranger build. They have so many limits on weapons I almost unsubscribed. I have used a certain play style since Morrowind. ESO does not give that open freedom with weapons like other Elder Scrolls games, I think they got the armor down pretty well. But the weapon options, not even close yet.

I dont think a change to the staff/sword system is needed (staffs are 2 handed in this game, and that's not likely to change).

I do think there is a need for additional weapon skill lines and weapon types, however. As always, the devs managed to leave out spears/polearms (why do so many games forget this weapon type, seriously?), and I think there's probably room for crossbows and such. Of course, you could argue that crossbows would fit better into the bow line, but I think they'd be deserving of an entirely different style of attacks (less AoE, more heavy/high powered single target attacks).
