An action or strategy carefully planned to achieve a specific end.
A plan of action or policy designed to achieve a major or overall aim.
You're just trying to mess with me, aren't you?
That beings said, I don't think your example places unreasonable requirements on pugs. It's basically recognising some new adds appeared, choosing aoe attack abilities to establish aggro, and popping a cooldown. Not exactly monumental levels of difficulty.
If a tank is not using cooldowns at the right time, a healer cannot carry them like in 50fp's. I think this is reasonable for boss encounters with specific mechanics, but not for group finder flashpoint trash.
True, but in 50 HM FPs any member of the group could basically carry.
As it stands, once you get geared up things become significantly easier. In my experience tank cooldowns are already largely unnecessary in a 69/72 mix.
