I'm fine with them pushing the power level/weirdness of walkers, just wish it was more in the 5CMC-6CMC slot where it's less likely to ruin formats than the 2-3CMC slots.
Like, WAR Sarkhan is sweet, powerful, and opens up an entirely new play pattern. But he costs 5 and has deckbuilding costs as well, so it doesn't matter that he looks busted when he works, because the costs all line up in such a way to mitigate it. The headliner Chandra from M20 terrified everyone, and has cool, unique effect. But it costs 6 mana, has a few blind spots, and its most "unparalleled" effect, the DoT Emblem, is dedicated to the long game, so it didn't actually break anything. Shit, even 5 mana Teferi, as strong as he is, isn't busted. The same people bitching about him all format were the same people who bitch anytime hard control is functional.
You get to do your hype/busted thing, but it doesn't break the format. The same costs aren't there in self-contained beastmode 3CMC walkers, so you get to do your shit AND bust the format.
