True, getting 20 people is harder than getting 15 but it also allows more room for multiples.
And no....having Flex won't make things easier to balance. Nor does the need to balance a fixed Mythic size have anything to do with the balance in Flex. The issue with a Fixed size in Mythic is simple....players don't want to be bothered with the roster boss but still want to try Mythic. They want the prestige of Mythic but don't have the players necessary to take part.
The frustration is understandable. But it also ignores why Blizzard chose this design for Mythic. Essentially....if you aren't willing or able to form a group, then Mythic isn't intended for you. Mythic...as it is currently designed and implemented...requires a fixed size. The 10/25 split had its own issues, its own problems and Blizzard solved them by implanting Flex for most and a Fixed size for the hardcore.
There is some flexibility in what that fixed size may be, but Blizzard settled on 20. So far, the main objection seems to be that players resent having to form 20 man groups. But even with Flex, Blizzard has a group wanting Flex to go down to 8 man raids. It's doubtful such problems would cease if Blizzard switched to 15 man Mythic....players would simply want 10 man.
Given Blizzards criteria and what they wanted from Mythic, a 20 man fixed raid size was best. It gave Blizzard the fixed raid size they wanted and needed, it gave Mythic groups a certain degree of flexibility in raid composition.
But they've presented such answers before and this was never good enough. Still, maybe Blizzard will change the role for Mythic in Legion....but, if they do, won't that cost it it's prestige and desireability?
