Yes you can move/press cooldowns, how is that relevant? The entire discussion is about a loss of potency that rides on the GCD, not whether or not you can hit off-GCD cooldowns or move your character. While the GCD from your stance activation is ticking your MT that needs you to swap with him is still tanking the boss, probably with a debuff. Of course you can plan around this, but that requires activating your stance early and losing more DPS, something WAR has never had to do. I can't listen to any argument that says tank swapping with a stance change on PLD/DRK in 3.x was not hot garbage compared to WAR, I'm sorry.
There absolutely was not always a cost, other than the lack of instantaneous mitigation intrinsic to Defiance, which imo is an argument rendered completely moot when you consider that since early 2.x after fixing WAR back in BCoB, it has had the most powerful and versatile cooldown suite out of all the tanks, hands down, and it is now arguably even more powerful with the addition of Rampart. Arguing that the lack of instant mitigation from swapping to Defiance was ever a true and real hindrance to the job in content is like arguing that WAR is squishier than the other tanks; it ain't true.
You cannot equate the lost gauge to a loss of 3 GCDs because that's like saying the potency of those GCDs is just gone, which it isn't, only the gauge is. So that statement is extremely misleading and is nowhere near spending a GCD doing zero damage.
I've said for years that the easiest way to balance tank stances is to simply put them all off-GCD and have Defiance refill your HP to make it instant mitigation. Dunno why they did this instead, but I honestly expected it. Swapping stances should cost something significant, or it should cost nothing. And for years it has been a DPS loss for 2 tanks and a minor mitigation hiccup for the other. Now its a DPS loss for all 3.
Most people are simply saying that it should go back to being costless, rather than suggesting ideas for a different cost since they don't like the current one.
What's really funny about this troll thread is that for years, WARs said: "if you nerf us instead of bringing DRK and PLD up to WAR's level, then we'll just have 3 tanks that are poorly designed" and now this thread is advocating that exact same approach from the other direction: make DRK and PLD's stance swapping even more garbage than it was in 3.x to bring it down to how bad we think we have it.
PLD loses a GCD both ways. That's ridiculous. DRK loses a GCD one way and an half of one the other (yes people always forget that turning Grit off is still on the GCD, even though it doesn't trigger it.), plus a sizeable chunk of a much more valuable resource.
And then there's the fact that if you burst out all your MP and then need to activate tank stance suddenly, you're screwed. Whereas if it worked like WAR, I could just floor my mana and still turn it on. Yes of course this can be played around, but by that same logic, so can the lack of instant mitigation inherent in Defiance. Grass is always greener I suppose.
Flag on the play: straw man.
I did not say that WAR's gauge should keep the cost it currently has. My entire post was simply justifying it having a cost at all, and pointing out that the cost of DRK and PLD's stances are still harsh enough from a DPS and resource standpoint that they don't require further nerfing. WAR's design right now is pretty garbage, I'll agree, and SE doesn't realize that they've built a job which they cannot adjust or tune or balance properly because pulling at any thread would unravel the entire tapestry of it. Beautiful things are often fragile.
I also prefaced my post the way I did because - get this - it is actually what I believe. WAR having all of its utility stripped away means its DPS should be lightspeed-better than PLD. Anyway, unless they're going to make all the stances costless, WAR's stances should have *some* kind of cost, preferably of a resource they can easily recover which was why I suggested buffs to their gauge generation.
