I’ve started playing GW2 on my MBP a week ago and during peak-moments (19:00h - 23:00h)I have found it very hard to play at all.
My FPS is 40+ so I’m not complaining on that end, but the lag/DC’ing can be very irritating. Especially because GW is such an rapid actionbased MMORPG where timing is an essential part of the gameplay.
But the Mac-version is still in Beta so there can only be better times ahead.
