I would like to ask you a question ... maybe stupid, on the first page you wrote that the other coins have integrated all in LTC ... I know when you create LTC also create doge, but we do not see why convert them all into ltc automatically? have you ever thought of making two separate wallet for those who would like to have even the Doge?
Yes, the possibility of paying merged-mined coins directly to miners was discussed before (see
here for example). The problem with such a feature is that it would complicate the accounting system and other things considerably. For instance, due to how merged mining works it would be hard to apply a fair PPS system directly to each secondary chain. It would also be rather difficult to allow only part of the pool to be paid in litecoins only, as I think that most miners would still prefer to be paid this way. Personally I must say that I'm pretty happy with the payout system we've been using since 2014. It keeps things simple, manageable, and easy to understand.
