All dps knows that if you mark 1-2-3, they must hit mark 3 than hard as you can.

Usually, i not mark trash mobs, as a paladin i can hold aggro ever the dps let me do it. Sometimes and very often, at start throwing "shield lob" and mobs running to me, bards start to aoe rotation brain dead. Then, the bard have the aggro and try to kite, pulling other trash.

I use shield lob, flash and scorn meanwhile the GCD it's running, then other flash and start to hit one mob using the chain combo. After that, tab other mob, fast blade + savage blade, tab other one and execute "Halone" over him. At this point, the first mob i hit need more aggro. I use this rotation trying that all mobs have the debuff strenght. If they 4 mob or more, flash is necessary to spam.

The worst encounter will be which you need stopcast one mob, because no generate aggro, need GCD casue flash and combo chain are the same. At this moment, one bard or BLM can aggro.
