Getting Owned - Help needed

[wackjob]

This is not a gripe post. I felt I used to play pretty solid 5/10 limit O8. I don't think variance is the cause of my suckness lately, but something I am doing wrong.

I have tightened up my play a lot. I try to value bet and value raise a lot, but I am losing a huge % of my showdowns.

What to do to get back to basics of just winning TAG O8?
FWIW I am a 1.5/100 BB winner at LHE(5/10, 10/20, 15/30). I just cannot seem to get my O8 game back. Are the players at Party vastly improved since the affiliate thing or is it more likely I made a change in my game to make me suck?
