I know that if I piss on a forest fire I technically helped.
Yes, but does that mean more tanks? Probably not. It’s the literal most boring role, and the least needed role, only relevant in small numbers for raiding, and in bigger numbers for Heroics which is content that will be outpaced and underplayed until P2 with the birb that drops a mount and P5 when Kael’Thas comes back.
Your other Druid friend has already stated that cata was best when we had dual spec, LFD, and satchels. We won’t have LFD which is really the crux as to why tanks became more relevant, and satchels as an incentive to actually do the instances consistently.
With dual spec only, you lack ease and incentive. It won’t fix the issue, now matter how many small pockets of people piss on the forest fire.
Except we’re not talking about respecc’ing, and it’s not as easy as you’re making it.
You’re ignoring the fact that only 3/9 classes can tank, most of those won’t go tank, ignoring the pvp OS or the farming OS, ignoring the fact that heroics aren’t needed as much day by day, and more.
You’re just coping, and honestly, I don’t believe you want dual spec to help the tank issue. You just want dual spec.
Except it’s not an all or nothing. You’re saying that as cope. It still leaves thousands of dps, IN A PERFECT WORLD, without tanks or even healers are that point. You’re still ignoring (read the comment above this one) and it’s really just cope.
We put in dual spec, we see a rise in tanks for 2-3 weeks, and then what. We’re back at square one with no tanks because they’re raid logging, in pvp spec, or in an instance with their friends, or getting paid to run people, or just doing their daily until they don’t need badges anymore, which just leaves dual spec as dual spec, not even a help to the tank problem at that point.
