Disgaea DS: I got to the final battle in Etna mode, and so far have gotten by butt kicked twice. Not utterly blown out of the water, but 'I need a better strategy oh fuck it I'll do another Item World run instead'. Basically, as the End Boss he gets a shitload of hit points and some really good equipment to let him one-shot most of my guys. I need to keep him from one-shotting more than one of them at a time. In the original Disgaea, I did this by having a Nekomata attack last using a super-kick power to catapult him out of my formation each time. No nekomata in Etna mode. I think I might have to resort to sacrificial lifting.
COH: Issue 13's a buggy pile of crap, according to the beta boards. This is why I don't play betas usually. The actual changes sound really nice except for some (not all) of the PPP changes. One of them is a big kick in the face for one of my level 50s, though -- it removes her pet, which she loves, for a power she doesn't want and will never use. I never play my level 50s anyway, though. Even more than I never play CoH anymore.
Warhammer: Gunbad Mountain was... not a total fiasco, although it started that way thanks to some frustrations relating to lag and scenarios and server disconnects and grenade turrets. Eventually we tagged along with a guild warband and did a few of the PQs -- basically, we tried two of the three paths, and on each one we beat the first PQ and then wiped against the second PQ. Despite having the lowest contribution of anyone, I got treasure both times, though. I doubt we'll be going back -- it's kind of neat, but a bit too difficult considering we had a *warband* going up against what should have been a fair fight for a single group, and having enemies respawn behind you, making you start all over after a team wipe, is really sucky.
