Hello,
what I mean by that: now that ascended gear is account-bound (and tpvp builds/gear/runes/sigils/etc. are just a matter of clicking to change); it is really mind-bending to manage all the gear items (go to a bank, put it in the bank, relog, go to a bank, equip).
My suggestion would still include having to go to a bank, but all the other things would be easier:
Let us save:
1. utility skills on the action bar
2. gear items (in tpvp add sigils and runes too as they are free to change)
3. traits
So basically it would enable us to save profiles for different game modes and remove the need to manually select every gear item/trait/rune/etc. You just open your bank tab and – if the required items are stored in your vault – you just click icons and your gear/traits and utilities change in matter of seconds. If you have all the gear you need in your backpack, then having to go to a bank is a non-issue ofc.
Besides simplicity it also allows you to forget about remembering every build in detail. When one playes more than 3 classes in pve and pvp too, things tend to get a little hectic.
So these are my two cents… Support, rally, complain! Whatever… just make Anet implement this.
