After using my trial I would like to give some feedback on this. First of all, I've been playing Guild Wars 1 for almost 10 years now but I never really picked up Guild Wars 2. I jumped straight into the game, used one of the many level 40 coupons I have to skip the early game and enabled the grind mode. I was surprised on how well it works! It does events, kills mobs and roams around the map. Perfect if you want to let it run over night or just want to watch how good it fights versus the mobs. ;-) I only got stuck once, which can be blamed on me. The bot wanted to kill some mobs underwater while I didn't have a water weapon equipped. Again, this is my fault.
What I liked the most is the assist mode. It basically turns the difficulty level from GW2 to easy. You do the movement and the bot does the killing. Now all the classes which are super annoying to control make fun again. Sadly I couldn't test it in PvP but I suppose it works just as great.
Overall this is a marvelous product and if I get a little bit more into GW2 I will definitely buy this. :-)
