I'm very confident Metamorphosis will be gone, the writing is on the wall, but not set in stone. The addition of Demon Hunters and the changes to Shadow Priests clearly make this a done deal. I feel bad for hardcore Demo locks. The whole time Blizzard said Demo was difficult to tune and OP in Demo form and yet now they're introducing DH's and Shadow with the same mechanics. Like wtf? I'd imagine a lot of Demo Locks will be re-rolling Shadow.
Why? They're basically turning Demo into the Necromancer spec from Diablo 2 except with demons instead of undead it sounds cool.
But Metamorphosis wasn't the point of what Kanrathed achieved. Fel infusion was. Metamorphosis was already an established thing in lore by then (considering it was two expansions old by that time), Jubeka's journals mention it. Just like they mention Kanrathed developing Dark Apotheosis form as an evolution of Metamorphosis long before he infused himself with the Fel and went mad. His Metamorphosis wasn't even a result of said infusion.
Also, lol at the careful part. Part of information on Class Halls from Blizzcon: "Warlocks overstep at the start of the expansion when the Order Hall is introduced, getting greedy and think they have more power over the Legion than they really do." Super careful.
Know your lore. Especially if you want to make an argument for class changes based on it.
These are verbs.
I know you did. But I really don't see the validity to saying that Warlocks are careful. They have always been power-hungry. And searching for new sources of powers, even if they aren't related to Fel or demons, as evident by Council of Black Harvest's activities. So even if Metamoprhosis is originally a Demon Hunter thing, it doesn't stop Warlocks from appropriating it, from lore perspective. There have always been cases of Warlocks toying with powers too strong them to control and burning themselves in the process. And I'm not sure if you admitting to mixing things up was related to the lore of Metamorphosis and Warlocks or verbs and adjectives, but if it's the latter it still leaves the issue of your explanation of lore reasons for removal of Metamorphosis being incorrect.
I cannot really make any statement to the whole lore thing but we saw that the Black Harvest will have a massive influence on the Warlock starting experience in Legion. If this is going to explain how or why we lose metamorphosis? I sort of hope so, because I would not really mind it if there was a story line for warlocks that explains it as a whole rather than just removing it because the Blizzard dev team feels that it never belonged to warlocks in the first place.
And yes, I mixed adjectives and verbs x_x
Try to keep your emotions in check in here, I don't want want to dole out infractions for basically nothing. Lore arguments and making sweeping declarements at this point of Legion is not very constructive.
