Limping with premium starting hands in a PLO8 cash game ?

I play in a local PLO8 single $5 blind (with straddles) cash game which tend to play very big with many preflop pots between $$150 and $400 everynight. Several Players tend to call pre a wide range of -EV hands. Even hands as strong as AA23 , 24ds I find myself sometimes limping into pots in this game - is this wrong ??
