Guild Wars 2

Seriously, after you buy all the things that you need where I spend it? Buying costumes? Making even more gold? Stocking gems? Making funny things like transforming and fireworks? Influence?

Lately I’ve been changing my build a lot too to try new types and weapons, this type of thing.

I’m out of ideas.

congratulations, you have beaten Guild Wars 2.

Charity. There is this charity in Borlis Pass wherein you have to pay the “poor” players there

I think I’ll buy the costumes and pets, then stock gems that worth more than gold, then when they release new stuff I can buy

Player hosted events like me :P

Other heros, super WvW wepons, all the skins, diffrent builds for your main, gems for max spaces or to save, there a lot you can even go as far as starting to flip the TP.

I’d save it for future items. You could insta-buy the first new legendary on the TP (could be armor or trinkets!)

If you have tons of gold, more than you can reasonably spend on anything and still be left with more.
1- invest in ectos and stock them up en masse – they are the real currency of the game
2 – Charity – give to people that are struggling, not those looking for a handout. There are plenty of them around. If you’re in a guild I’m sure you’ll find some that try but RNG hates them.
