Tanks on beta and PTR are totally broken and seem to go live like that if patch comes soon.
Its not dps, its us.

I mean lets have a look. I was doing dungeons on PTR and Beta. My group had spriest, lock and shaman.. it was nightmare.
I was building threat for 20 seconds on mob ALONE and spriest comes from afk and uses TWO ABILITIES and PULLS AGGRO.
The worst example is when hunter came on other group and hes pet had FREAKING GROWL on that did MORE THREAT than I DID for 7 seconds.

This cannot be intended change, the tanks are just broken. The threat has gone so that you might do 50% what you use to do at max. It would be totally impossible to tank current raids with these threat numbers. DPS raises to roof and tank threat lowers so that hunter pets growl overaggroes you? If the threat is balanced at 85 whats the point of playing for last months if its impossible to tank like this? It's legitimate question.

I dont mind harder tanking but this is just "what a heck?". The spriest ended up tanking 60% of the instance because I just couldnt hold aggro for more than taunt+2 seconds.
And I'm wearing ICC25 normal and hc gear and I KNOW what I'm doing and I HAD time on the mobs.

Note: Spriest was using mindspike that "causes high threat" now but its still not possible to pull aggro with one dot and one mindspike, now is it?
