Hm...I think my feelings for Fusion Fall are best described as "lukewarm." I do think they have managed to fix some of the big issues that arose back in April, and that has raised my spirits a little bit. As far as chat goes, I really don't have an opinion of it. As long as it never goes back to the way it was in April, I will be pleased.
The Ice King delay was a bit of a spirit breaker, but after exploring the castle, I think it may have been worth it. The update was pretty good, so the fact that they screwed up and had to inadverdantly postpone the thing was reconciled...kinda.

I think Fusion Fall been moving in the right direction since the F2P fiasco in April, and as long as they keep trying to get the game back to where it was before F2P, I think Fusion Fall still has a future.
