Don't blame GC, he wasn't the person who made the change he's just the one employed to tell you about it

@Imnick: There isn't even a change here.

The community read what they wanted. They saw "taunt" in the tooltip and went "ZOMG DEMO TANK SPEC". GC is just rightly informing them that they're idiots for thinking that. It was pretty obvious to me that this was a situational emergency button type thing.

No wonder Blizzard hates data mining.

No, we saw a permanent demon form, a taunt, tank-level threat boost, and tank-level mitigation.

Additionally, you lose out on your mastery buff to damage if you take the glpyh, as well as losing damage from various other sources, making it not viable if you want to do competitive damage.

Kaga, here's a thorough breakdown of what Demo warlocks are currently constructed to do in Mists and what the glyph does in Mists: http://us.battle.net/wow/en/forum/topic/4254517075?page=1#1

It screams "tank" from one end to the other. In addition, since changing glyphs isn't possible in the middle of combat, it's not feasible to use it as a "situational emergency button type thing", so the only idiot here is you. The rest of us actually did some research around said data mining and constructed our arguments on what was presented like normal, rational people.

What they've done is create a glyph and an entire system of functioning (Metamorphosis, Nether Plating(!)) that is essentially a gimmick. GC says "character customization" but no one playing DPS wants to hamper their DPS using their signature ability on the off-chance that the tank might go down and they have to take over. It's not just a gimmick. It's a stupid gimmick. Why waste developer time and space on such a thing? The natural assumption is that they're not wasting time but are, instead, adding the option to tank which is not only an innovative idea but one that contributes to the game as a whole since tanks are the bottleneck in the LFD and LFR queues and another spec is a bonus to everyone.

Try thinking before posting next time.

@Boobah

But you saw that BEFORE you even got to test it. You have no idea if that would have worked they way you thought, in reality. Perhaps it would have been better if he said nothing and let people crash and burn themselves. This is just like the people thinking they would get auto invites to beta for signing up to AP.

"Historically, warlocks felt tankier than other casters and could even off-tank some encounters. We have made an effort in Mists to recapture some of that flavor. [...] You might be able to off-tank adds or pick up an actual boss for a short period of time if the tank goes down.

So the whole point of the redesign is to create an off-tank spec for warlocks, in an expansion that's introducing a new tanking class.

Clearly people are angry about this decision, but I'm just confused at this point...
