Chain pull.. is that bad?

[Lollie]

If by chain pulling you mean "boss-to-boss" pulling

No what is being discussed is 'stop and go' vs 'stop and kill', gauging appropriate pack size is a separate issue.

...And clarifying its not that i take mobs at 10% health and then go to the next group. I only do it to build up hate. 2-3 rotations aprox...

2-3 rotations is about long enough for most buffs to run their course so it isn't quite as bad. That said there is only one class/job that would benefit from keeping buffs going and that is pug/mnk with greased lightning, and you may very well yank whatever mob they are hitting out of the way on a gl refresh skill negating the whole benefit of that unless you are paying close attention to them anyway. Because of their TP usage if they don't get that increased resource recovery they are either going to run out of TP or have to resort to switching to single target to avoid that.
