My main is a paladin, i also have druid, warrior and dk alts all with a tank spec. If i were to rank them of ease of chain pulling (in 5man dungeons, were mobs die in less than 10seconds) druid first then warrior then paladin and way behind would be a DK.
DK has 30sec cd on DND 8 sec cd on HB. (Ive only tanked as frost spec, pls update me if its easier to chain pull with other specs)
Paladins abilitys are 6-10sec cds.
Warriors have tc on 6sec cd also cleave on no cd.
Druids have no cd to stop them chain pulling.
Id like bit of advice for my dk on how to make chain pulling easier on him? and how would you see differences on chain pulling between tank classes
