I thought we did great, theres just somethings you cant learn until you have seen them a few times, i have no doubt we can down him next week and i seriously want to start farming him

Sunday night Squid
We have it all licked up to the last part which is awesome
Couple things i can personally think of that might help..
With a champ in my group i can shield of the dundain him when all the tenticles spawn and he/she can suck up all the agro then everyone else charge in (saves my last stand in harms way)x2 captain and champs is even better but not essential as we proved on sunday with none.
An extra person with me on tenticles(not sure if i struggled cos we lost a hunter) or even better a champ standing between tenticle and watcher who switches sides with my tenticle group,again not essential but since we dont have it on farm we need to give ourselves the best possible chance, once its licked then we can go 10 man it
The hunter tanking the target tenticle has to be lightning fast getting the agro i got new tenticle agro a few times took some big hits i probably have time to wait
When hitting the watcher i found you have to be standing riiiiiight on the edge of the bridge and when he inducts you should really move back as far as you can (I even used to take a swim at this point)
Use your pots regular, dont wait for heals and power
You all know this better than i do i still forget
