the pool is too huge its almost impossible to attain higher then LTC profitability.
when coins are exchanged the price thus profitability drops.
its been fun guys, i'm switching to doge as I expect higher exchange rates when their 1.6 patch starts and the block reward is halved

Yup, multipools are getting too big to be profitable. Wafflepool is only mining some coins that do have a very large network hashrate. They can't do anything else, because the smaller (more profitable) coins will get hammered by a 17 or 35+ GH/s pool.
