Now hear me out, as an ele, I agree that giving weapon swapping to elementalists would be overpowered. But Anet can give it to us, with a slight twist, and I think it will make a lot of people happy.
What I am proposing is that Anet give us weapon swapping just like every other class, but only let us switch weapons while out of combat. Mechanically is will be the same, while reducing some of the inventory clutter. I hate having to fill my entire screen with my Hero panel, hunting for that one, special icon that I am looking for in a dire situation, (running off cliffs, or through fire and whatnot) just to equip a weapon.
I feel that elementalists are very cumbersome when it comes to changing weapons, and I feel that this slight change will help a lot. Besides, we aren’t using the “~” key for anything else!
