no offense BUT there is no ''right'' and ''wrong'' there is 1. personal preference and 2. not all trash packs are the same.
Personally i like the dps attacking what i am attacking.. it makes it harder for them to pull off me ( they still do though ... no one bothers to drop threat during trash )
To make it easier for them use either verbal calls or marks .. for example bind flame on a easy key and mark your current kill target with it .. when it drops mark something else ..etc..
If the DPS start whacking random targets they'd better be geared enough to take the damage.. especially so in random LFG groups.
In actual ops I don't even try to tank trash anymore as no one bothers to follow any type of a kill order
and to be fair trash in the new instances is so much easier than in EV and KP ( especially in 16 man )
This is essentially the opposite of everything I have found as a tank. As a vanguard I have a lot of aoe at my disposal, which means I pretty much prefer to run flashpoints without CC. As such, I generally operate on the idea that a sticky grenade or aoe taunt alone will keep the regular or weak mobs occupied long enough to get dead.
If the dps decides instead to all pile on the 1-2 elites then the healer is worked harder, making it more likely for some small sub mob to break off me and onto the healer, which means I have to see the healer's health go down, identify the breakaway, break rotation to pick him up, then return. All the while taking 5-6 mobs worth of attacks.
If instead dps simply assumes Weakest--> strongest kill priority then by and large the weak mobs will be dead before the taunt wears off/sticky grenade aggro is lost/etc.
In an operation if the dps doesn't stick on the tank's target then all of a sudden trash is going to hit hard enough to either overtax the healer or get the dps dead.
Whilst everyone has their own opinion, personally reading through your list I'd have to say I would probably rather not run content with you as my tank.
