I agree with this, too. If they're going to confine us to class = weapon, then they need to mix capabilities. A spear using tank, or spear using caster, or a damage dealing sword user, etc. It's one of the problems I have with Neverwinter. Thieves only use daggers which is against regular D&D where they can use many different weapons. It ends up having everyone using the same thing with no real variety. Sure it simplifies life on their side, but it losing flexibility for the player.
So if they're going to be so limiting, then they need to give options. If i want to be a damage dealing sword user, then there should be an option for that. Especially since sword is so popular with people to begin with. Heh, I made a thread about this very topic on the FFXIV forums and there was a lot of support for more choices. If different classes could use different weapons, then that would be a different story.
