Here's the thing
I can't with main sub( and some lurkers here) and their hypocrisy about mydei. "He's good enough you all want him to powercreap x and y it's not good for the game health bla bla" Blud stfu. Acting like if mydei won't powercreap anyone, powercreap won't happen. Same people wouldn't shut up if castorise have the same damage as a dps from 2.0. Mydei kit is controversial and restrictive with little pay off. What I mean about pay off is acheron and herta for example. Acheron e0 want LC jiaoqiu and although can use one harmony like robin she's a two nihility teammate. Herta want another erudition and aoe. But they get big pp damage as rewards and they are really flexible in most content. They have bunch of options. Mydei on the other hand has an element that is conflicted with his goddamn kit doesn't has THE hp support doesn't have the best synergy with any harmony going rogue which is extremely uncomfortable if you plan later that content isn't catered to him and all of this with a subpar damage. Ain't no way people call it he's fine he's fine he doesn't need buffs or changes.
Edit: this is mydei sub btw. You can get your worries about game health to main sub I'm pretty sure the echo chamber you need is there. Here we want to pick a DPS that might decide our whole experience in patch 3.x.
