as said on their main website, all players on pc and mac get a 50% xp bonus

go farm!
"his is 50% on top of all other bonuses, so if you’re running T6 for 1600% exp bonus, it’s 2400% right now. (And even larger if you’re doing multiplayer, wearing +exp% gear, etc.)"
from what i've heard it will last till 24th march as well!
gogogo!
thanks are appreciated O.o ^^
