All in fests

[pokerdirty]

I've been playing pokerroom.com's SnGs for 18 months now, and one thing is a guarantee everytime you play.....once it is heads up, the match will become an all in fest. My roommate plays on Party, and I see that it's the same way for him, but with party, it's more understandable considering the smaller chip stacks. But at pokerroom, the starting chip stacks are 1500, leaving the average HU at 7500, with blind levels at around 100-200 when HU begins. Is it only like this because I'm at the 11s? Or will I be doomed to this all in fest no matter what level i'm playing at?
