That's such a bullshit attitude. Theres always room for improvement. In his case quite a lot :P
I checked the longest Garrosh attempt (9:00), His eternal flame uptime was 17%. He missed millions of self heals because of that.
He used Divine protection 4 times (30 sec CD so in theory could have used it 18 times) The prot 2 piece has a nice synergy with DP so he should really use DP on cooldown (it gives you a 10 sec HoT for 75% of the damage taken in the previous 10 sec)
Apart from that hes using the dps cloak. Not a good idea progressing on a boss that hits like a truck.
Bottom line is he can help out the healers more, hes also missing a free cheat death ability for *moar deeps*
