Oh, I remember you. I was the one who told you to check your other members.
This is one of the things that matters, but I'll try to comment her performance without mentioning others this time.
The biggest surprise was Galakras, she should do much more there. I compared her logs with mine and it seems like she's not using enough Havoc and Shadowburn. Probably the same on other bosses too. Destro is all about this stuff so she should use them. I'm not the best and fastest player anyway and my latest Galakras kill took 3 mins longer than yours, but the log says 14 Havocs, 102 Shadowburns, she did 1 Havoc, 30 Shadowburns.
Here's a little something that might help her:
Code:
/cast [@mouseover, nodead, harm, exists] Havoc; Havoc
Now for the gear and setup, she'd be better with a bit higher haste and KTT trinket, but I understand it's easy to say "get a trinket". She should be rolling coin on trinket bosses though. Also on some fights (Galakras again for example) it's cool to use the cleave trinket.
