Hello, I make this comment to express your opinion of what I am going to propose, as on another game, I found that practises, why not to add a bar (as the current skills among 5 for example, which could move on the screen as you think best, but with items such as weapons to avoid opening items of heroin either for example increases, bananas embroidered (cf WvW, or Pve) or other things who could make win you a mini lapse of time, personally she would serve me a lot, as I play practically that in WvW, the change of weapon really is (annoying) to open all the time its inventory, on a former game, I just had to crinkle or to press the command or the item was placed in this flexible bar.
In your keyboards.
