I have no problem with DOGE, but I think it won't change anything if the dev lists DOGE. Deposit and withdrawal via LTC is near free, so adding cheaper alternative is just too much work (with little impact).
I think that the added Deposit & Withdraw option using LTC is a win & win solution.
Doge is indeed one good choice, but with the price that is changing too fast at this time, maybe the dev will think more about adding the Deposit & Withdraw option with DOGE. It is only more profitable for the Player but very detrimental to Rollbit.
