I run a multipool... that's literally what we do-- we profit switch to get the best return. Mining DRK at a 20% loss will not make any of our miners happy-- as ultimately they don't get paid out in DRK anyway.. to them it's just a 20% loss of revenue.
Well if you find it difficult to comply with the intentions of the community and the development team, best we leave things there then. If you guys are paying out in BTC or something other than DRK, you are part of the reason for the coin 'not being profitable to mine'.
In any event, if its not profitable, you wouldn't be switching to mine it, so no loss for you either way.
