1. Hero build editor: save/load equipment + traits, with just one click, to/from bank equipment (see 1.1). Unlock with gems.
1.1 Bank equipment: to store only account/soul bound armor, weapons and trinkets. Unlock with gems.
2. Make all equipment available from all type of game (PvE/WvW/PvP), for example, you can make an infused ring/backitem, only if you do fractals, but this is very usefull on WvW.
2.1 The reward track on WvW and PvP it was a very nice addon to balance the difference, but the gap still exists, like legendary back item, in WvW you don’t have it.
I don’t like to make the list longer, and i write the most important features that are very useful and we need them right now in the game.
