I think that funcom should make it so that when I press a greyed out combo (because I don't have the right weapon equipped) that my character should automatically swap weapons and use the combo I hit. This is where it would really help out.
Say I am on my barb and I have both wreck armors and ww are used and the boss has all shields up. I can't do an upheaval (white hits would hit harder) and I have the other 2 combos that hit form the other angles used. The best option is to switch weapons and do a butcher/2h upheaval. However, I a raid there is a lot of lag so when I switch weapons I may cut the current combo short or I may switch weapons twice due to lag or the weapon swap will take way too long. This is not to mention that I can't pre-load a 2h combo if I am currently doing a dual wield combo. Automatic weapon swapping would fix all these issues.
In pvp it is still the same scenario. Usually the lag isn't quite as bad because there are less ppl but when I am in a siege it is way worse in which case I would really need this. Also because pvp is so fast paced, and if I do have the slightest bit of latency at the time (pve there is constant latency) I will have all the problems listed in the above paragraph.
I know I am not speaking just for myself because a lot of people in ts/vent tell me that the main reason why they have problems with a barb (also applies to conq) is the weapon switching and this would be an easy fix. I if you hit a white combo (because you have wrong weapon equipped) you character will automatically swap weapons and perform the combo. Easy fix that solves all lag issues.
