yup, some new tanks go rely too much, some rely too little, flash never been and never will be single target holder, nor its effective past initial aggro of multimob pull, well expect when you start have 5+ monsters in aoe field...by then flash spamm is what you have left. too much= you lack aggro on those few you could hold more easily with combo rotating, too little= you just lost initial aggro against healer and all mobs are running nuts around arena.
