auto exchange fee seem a bit excessive/high at 2% when most exchanges charge less than 1%. Whats the justification for such a high fee other than greed?

I have no problem with charging for a fee for the automation but the 2% fee seems a bit excessive, on top of the pool fee.

For an example Mintpal charges 0.15% and poloniex 0.20%. Cryptsy is at 0.2% for buys and 0.3% for sells

Can you please give a reason for such a high fee? Which exchange are you trading on?

Maybe change the autoexchange fee to something more reasonable? Like say 0.5% (like your pool fee)?  I guess thats why your pool fee is so low, coz you gouge (unsuspecting) users that use auto-exchange? Just seems greedy to me when the going rate is about 0.2%.
