That bloody whirlwind magic spell is a real bugger! I've been playing with my brother & a good mate, one as a healer & the other as a warrior (naturally I'm an archer), great fun despite some rage worthy moments with instant target switching attacks when fighting bosses just wiping one of us out (usually the warrior who is fond of bouncing around because he put so many points into his first skill)
I hope people are finding a similar problem with the agro, no matter how hard we try, on the longer fights I always gain the mob's attention (I can only assume because I'm dealing the most damage) and particularly on boss fights where I end up leaping around like a nutter, having invested heavily in the second skill (sniping is great for groups of mobs, but terrible for bosses past the first three or four barrages, you just get obliterated) in order to avoid the attacks.
The poor warrior is on knockdown & "wtf is behind Tenne" duty because my brother was rather awful at it, his way of informing me I was backing into four monsters was to go "mmmmwweeweeemwemweee!" into his microphone.
Anyway, needless to say, I've written my experiences of moments that amused me so I'd give this a thumbs up, but only if you have a couple of people to play with, it's a different experience solo.
