There are some Scrypt pools that don't work well with high-capability ASIC miners, though fewer than there were 2 years ago before the Innosilicon A2, KNC Titan, and Alcheminer showed up.

 The L3+ is NOT "specialized for Litecoin", it is specialized for Scrypt mining.

 TheBlocksFactory should work well for you as a DGB pool on Scrypt.

 DOGE - don't bother, it's a merge-mined coin not worth mining it on it's own.

 I forget what pool I was using briefly to mine GAME.
