Guild Wars 2

Anet should really give us an option to either remove the pet completely or when you stow it away it should stay away till called upon im busy trying to get the lair light foot achievement but my pet keeps triggering the traps… and i cant stow it away since if i get attacked by accident oh look pet is back… 4 hours in still trying to get the friggen achievement

The time is short and even if they’ll apply such option it won’t be in 2 days (and honestly, I don’t think they’ll ever do it):
If you really can’t do it with your ranger may I suggest you to use another character (or to create one, if you have only that one)? After all every character get levelled up to level 80 and if you go with someone you know or with random people wich are going in there too it shouldn’t be a big issue to reach the entrance…
As for Canach, he’s quite pathetic when comes to direct damage (I’m not saying it will be easy as if you were a true level 80 character, but it should be viable), so with some attention it should be possible.
