Not quite
X5Dragon. You talk about fantastic new defensive Pokemon, but which are they? We have Togekiss, Goodra, and what else as contenders? Yeah it's true that GF nerfed many offensive tools, such as weather and high BP moves, but they more than made up for it in terms of power creep with the introduction of MEvos. How will stall deal with Mega Lucario and Mega Garchomp, Pokemon with incredible resilience to passive damage and the ability to 2HKO the whole metagame UNBOOSTED? Let alone Mega Medicham and Mega Gengar, the first of which won't be used a lot due to its frailness and relatively low Speed compared to other MEvos and the latter of which will get banned pretty fast imo, but they may be things for stall to look out regardless. Mega Lucario and Mega Garchomp don't even compare to the best wallbreakers of 5th gen, such as Kyurem-B and Hydreigon, the first of which was weak as fuck to residual and the latter of which relied on stat dropping moves and could be worn down due to LO. I know we are missing a lot of factors right now, but with the things we know stall definitely seems to have gotten a hit.
GF really did more harm than good with MEvos, as far as stall is concerned. I honestly fail to get what they were thinking. Why increase the overall power of special attackers and weather, just to make the power creep even bigger by increasing MEvos? Why not create some good defensive MEvos to balance the power creep a bit? Don't get me wrong, i know that GF doesn't care a lot about balance and releases offensive MEvos because they sell more and appeal more to the general public, but it's not like i am asking to have half offensive and half defensive MEvos. All i am asking is a fucking couple of good defensive MEvos, is it that hard? 3, 4, 5, or 6 would do the trick, out of the dozens of offensive ones we got. It's not like it's hard to do it, just give to the MEvo Regenerator or give the MEvo to an already good defensive Pokemon with reliable recovery. But no, all they could think about is fucking Mega Venusaur, a laughable excuse of a defensive Pokemon that can't even switch into Water-types (Scald) as if it gets burned it loses 25% of its health every time it comes in with SR up, and has no reliable recovery as well.
Really sad times for defensive teams indeed...
