In regards to T8 masters in karnors - just cast a lazy eye over the named mobs in lootdb- if you are a member [free], the site gives out percentages - a rough idea of the drops is around 70% for the set legendary items ('bout 4 per name - steel chest) and about 4ish% for the lvl 71-75ish masters (exquisite chest) - good thing about the exquisite chests is that they appear to be 'guaranteed' masters as I can't see any fabled items listed for karnors at all - remaining percentag is trash loot in the old wooden boxes

So given the percentages for master drops - it is definately worth 'speed' grinding the names to basically increase your chances of walking out of there with a master in your hot hands - the bruiser definately sounds like a winner with that in mind

There actually are two racetracks in karnors which I tend to use if I go there - I'll draw a picture or something and tack it on the end of this thread for you - definately not the 'only' way to do karnors, but I seem to find it fast enough

The 'running' trick would work very well with the bruiser and feign - might even get out of killing the end mob in the rhino corner too making it a little faster to get inside

SKs are well know as the better DPS tanks - but they probably, imho, are the least likely to sustain multi-mob damage of all the heavy [plate] tanks - hence why I hinted towards getting a 2nd healer to keep the sk upright (e.g., defiler's ward allowing your wardens HoTs to do their job topping up the SK, etc)
