If what you enjoy can be done, then do it. Different players will build and succeed with different lists. I would have struggled with Kedzio's 5 khawarij list, because that's way too much points for not enough durability for me. Does that mean it's bad? No. Does that mean it isn't competitive? No. I'd build a list completely different from that. And I'd do better with my list than that one. But some people will do better with the efficiency of 5 khawarij than they would with the extra orders. Or would really value the raw threat of Tarik more than I do, or be more able to leverage it as a strength. Personally, I'll be sticking with my mixed core, my 15ish order lists, and my unhealthy obsession with mukhtar. Not because it's objectively better than other options, but because it works for me.
