A few quick questions.
I would say it’s your “gold” as in mystic coins.
However, you do need a stack of Coins if your going for a HoT Legendary. And seems like Anet is back on track on releasing the legendarys for HoT. So might be a good idea to hold on to 1 full stack.
I would say probably Warrior, as they have access to most of the melee weapons, and have good mobility and health.
I’ve just started the collections quest for the new legendary Axe, so I guess I’ll save the coins. Thanks allot
