For max reductions as close to the end of the cast bar as u can get(depends on latency) you want the buff icon to appear before the cast bar is finished to register(depends on the attack some attack have a longer animation and can be mig later i think)
No in fact the 30% skills usually have the highest cds in boss fight that will take more the its duration its best if used first. If the fight is shorter use it the mig the highest hitting attack.
In big trash pulls the same applies, fast packs? use it lower cds so they will be up again.
I assume u mean damage rotation and yes. but it also depends on how many mobs u pull. I don't play pld so i cant give tips here.
As the tank you are the leader of the party its up 2 u. You wont be able to pull wall to wall out right, but if u try pulling 2 packs then 3 packs you will eventually learn how to do wall to walls.
Generally wall to wall is the optimum strat for dungs. They are the fastest ways to get to end boss, and earn a lot of commendations. but they take time to learn.
generally yes u want to spam aoes until there are 2-3 mobs, at this point depending on your healer's mana just start to pull the next set of packs.
This is a good idea you want to ease your group into larger packs. pull 2 then 3 etc. You want to always be pushing ur group just alittle bit harder. But never to point of a wipe that costs more time, then if you just pulled 1-2 packs less.(unless ur wall -wall pulling then even if you die, if you have killed enough mobs its more efficient then pilling 2-3 packs)
As a rule, if you healer has mana you are good, make sure they are around 10-20% mana before you think of slowing down.
on wall to wall pulls. if your healer is not pumping(out healing the damage) but still has mana you can pop ur sprint and run out of the range of the mobs autos. make sure to stay in your healers range by running back and forth. this will give you healer time to heal you and dps time to kill the mobs
