If that's what you're crew needs to motivate them to play better, great. It's disincentive to many more though.
again this change hurts people who run progression the most
story mode ops are easy
hard mode flashpoints are easy
if you find yourself consistently dieing in these, there is a problem, even with a casual in the group, it's not hard to complete these, even with people running completely wrong specs, it's not hard to complete these at all.
Hell i had a guildie running powertech dps for a SM KP that was never even in melee range, meaning he wasn't doing his rotation properly. there is a LOT of leeway for casuals
