Now that you've clarified what "garbage" means, I suppose that it makes a bit of sense. You're playing starting hands that have good potentiol for straights/flushes more often, and because of the huge number of limpers in every pot you can get a nice return on a straight or a flush. If you start playing 72o just because it costs a penny then I'd have to say that's an obvious mistake but it doesn't sound like you're doing that.
