Asking for both is a bit of a fantasy.
Are you serious, bro?
That's the exact kind of argument I remembered back in the old "NOOOOOOO, making playable Pagans is a waste of time. Give us a college of cardinals NOOOOOOOWWWWWWWWWW!!!!!" which was incredibly, incredibly prevalent back then.
Until Paradox says "CKIII is on the horizon and this is basically it for CKII", to complain that one existing will prevent the other from existing is a creation of self-entitled silly goosery.
And last I checked, Phase Two was meant to be at least four DLCs, with Rajas of India now being number two. What do you think those other two will be, especially given that they've expressed before a desire to focus more on the roleplaying aspect of the game? I somehow doubt it'll be Zulus and Pueblo.
