Damn, been holding off playing multiplayer since I wanted to wait for my friend, but I'm nearly done with the 9 star (offline) quests already. Got too into it, should probably just go online now...
Most of the monsters aren't as hard as I remembered, and most of the new ones so far aren't too difficult. My first death (and only failed mission) was against Pink Rathian, since all of her added attacks seemed to be aimed at the blindspots I'd normally exploit. I didn't bring antidotes since I didn't expect to be hit by her tail (damn diagonal tail swipe), and that side bite with the added explosion is killer, the range on it is freakin huge! When she was weak I got impatient and planted a trap just as she decides to leave the zone, gotta love that.
I really love fighting new monsters for the first time, though. Figuring out their attack patterns and exploiting them in the same fight is too fun.
Adding everyone's name on my flist now, my NNID is cordlc, add me!
