Guild Wars 2

So today i noticed i can use my Items (harpy feathers, order of whispers spy kits, ROCKS, etc..) on the arena, and thats pretty op, i think they should disable them.
I had 2 pets fighting and i went stealth to eviserate the oponent and then perma cc’d him with the rock, pretty balanced :P.

Had the same problem, had a comander tag on my beta elementalist and as soon as i changed maps my game crushed and couldn’t log in in any of my characters, beta or non beta

after killing grenth the path bugs and cannot be continued, this happened to me twice in a row, i dont know if it just happens to me, i tried several ways of debugging it, but i could not.
(sorry for my english),
This is with the 31/3/2015 patch
