I realize English may not be your first language, but at least using proper capitalization and a spell checker would make your post much easier to read.
personally the changes to druids are a bit indifferent at the moment. its like we have someone changing our stuff to sort PVP or dps issues and then someone comes along with totally different ideas to make changes to tanking and survability.
Consider before previous patches with my character.
i had 50% crit over 51% dodge and armor mitigation in the 70% mark. we also had exta 10% stam bonus.
Ofc those days are gone ad we have what we have.
around 30% crit and dodge and 64% ish reduction and a lot less stam than we could have had.
so druids have been stacking heavy stam for last couple of patches and its worked fine and indeed helps with Boss fights with savage defence as the vengence ranks up.
But many boss fight mechanics now call for tank swapping or runnning about up and down a spiders web for instance. in this time we have the chance to loose out vengence stack and thus our AP goes back to normal adn i'm back to my 6kish SD shield that may or may not be up when i engage the boss or target again.
Add to the mix now the removal of basic threat on most of our rotation attacks as bears. we can alwasy use beserk for every pull or when threat is sticky , we cant always rely on missdirest or melee or healers not to over agro in switches of fight mechanics.
now one thing i have been doing is using my dps trickets in trash pulls. this works and from gear that other druids have got from recent stuff in firelands the added agility and base damage they kicking out they have less of a threat issue.
( i normally switch to unheeded warning and fluid death ) The dps trinkets solve hit cap base damage and also add very quickly around 700 agility.
Agility as we all know is dodge ap crit etc and we dont need to harp on about that , but the get me out of jail of the tank trinkets and the stamina is missed when things get sticky.
so i think until druids start to gear up we goign to have this stam vs agil question for a few months.
personally i like having tonnes of stam but the other tanks now are about the same so we have to look at our nextbest friend which is agility.so i trying out changes i've reforged to get hip and soft expertise cap to help with both threat but also if you miss dodge or parry you dont get your 50% chance at a SD proc so what ever you got in the way of stam or agility it wont matter . So the caps solve 2 problems we have at THIS TIME probbaly be differrent in a month or 3 of gear gains.
I've then gone for agility and with Pulverise up i got 40% crit or more. I also have more armor ap and dodge all of which work before vengence is even ticking up so pull wise and changign tank or mechanics mid fight i'm better off. lets face it the tactics needed in many fights now dont allow for tank and spank for a good percenatge of the fight.
so i've gemmed to match my sockets. red=agil, blue=stam( the odd hit gem) yellow =dodge+stam. this way i get more out of my gear and also if i have to go cat mode when a tank switch occures or it becomes a one tank and spank phase at the end of the fight i'm not as useless as i would be full of stam.
