I had good luck last night.
Got several games with varying party sizes from 2-5. The party size was typically equal. Played quite a bit of Team Slayer. It was a good night and overall things seemed to be working better.
There are still some issues though. When I had a guest, the framerate was terrible. This typically happened on the newer H2A maps, but it was noticeable enough that it affected the game play. The splitscreen on H4 is pure garbage. It puts black boxes on the left and the right of the screen, and everything is condensed down. It's puzzling why it's that way.
I also played some customs and ran into two glaring issues. One is (this could be a host problem not knowing the menus), he was unable to allow us to set multiple teams. We wanted to do a 2v2v2v2, and he couldn't find it. Was this left out? Or was the host just ignorant to it's presence?
The other issue was a broken respawn timer. This only happened on H2 Classic. Basically I would die, and the respawn timer was stuck at 9. It would stay this way for a couple of minutes, then randomly decide to let me respawn and tick down. It happened over a variety of game types, and was happening to several guys in my game. That was really frustrating especially when playing CTF, KOTH, and Bomb.
I had a good time overall though. Just iron out the bugs and I'll be happy, because the gameplay is still golden.
