Guild Wars 2

Although I installed gw2 onto another drive, I realize inside My Documents, gw2 had specially created another folder called Guild Wars 2.

is this folder suppose to be empty cause I do not see anything in it.

what does this folder do? Like save crash file and stuff? Or can I just delete it since its empty

Does any guild from TC uses teamspeak 3 instead of mumble? I dislike the fact that most guilds in TC shares the same mumble ( 10k slots ) , does any active guild use only teamspeak 3 and doesn’t share with other guilds?

Just wondering, i don’t intend to change guild though.

If each crafting profession only gives 10 level for maxing it at 400 ( some are 500 but its not important )

Assuming I’m level 50 now , I only need to max 3 profession to reach 80 and thats it?

I can max another 5 profession on a new character?

If i need to make items , I just have to switch between characters to make em eh?
