Wow, can people not read? The OP is pretty clear, he is only suggesting breath bar for when your aquabreather is not equipped. So many irrelevant posts...
... what people are asking here is a bit silly because they are asking for is to make all high end Karma/Token items into a deposit with 100% refund when you do not want your armor/weapon anymore...
It doesn't need to be like that, it could be on a timer, say you buy the wrong armour, you have an hour to sell it back or then it's too late. If you equip the armour you can't sell back.
I must say Sylvari cultural armors are the worst of them all. Difference between tiers is how the leaves are arranged.
Should've incorporated more elements related to plants, nature; bark, vines, water, earth(dirt,rocks), etc..
No way! The heavy T3 headpiece was one of the reasons I decided to roll Sylvari.
