Guild Wars 2

My game recently started crashing/freezing during gameplay. It’s happening randomly depending on what I am doing ingame. I tried repairing the game, lowering my graphics, It’s still happening.

Any ideas as on how to fix this?

Thanks!

I like the wolf overall, it has nice CC (fear 2s) on its F2 ability and the leap knockdown, I also like either the red moa/jungle stalker for buffs. For dungeons I use the arctodus as a second pet but my wolf never really leave my side.
