Yes. Get rid of them immediately or, preferably, re-tune them to 2-man heroics. I'm an obsessive completist when it comes to quests and I've been on Nar Shaddaa for TWO FREAKING DAYS trying to do these stupid quests. I'm going to have to skip them and the OCD in me is going to throw a fit.
Seriously, it's impossible to find groups for these. I play a healer. It's just getting ridiculous at this point. I'd love to see an option to re-tune these quests to 2 man when you can't find 4. "Join an active guild" is not a viable solution. I'm IN an active guild with friends, none of them have alts my level, and if I felt like it I could ask for a run through, but I don't. "Come back when you're higher level" is not a viable solution. I should not have to come back to a quest that offers absolutely nothing for me once I've out-leveled it.
As for the crowd spouting such useless nonsense as "flashpoints are hard to group for, should they be removed", get real. Flashpoints offer plenty for the effort--gear, social points, etc. Heroic quests? Oh, cool, I got some gear that offers a marginal improvement over my current gear, or is inferior. Oh, cool, some xp. I could have ground out more than that in the time it took to get a group.
Heroic quests are not the same as flashpoints. The reward is not worht the time invested. They need to be addressed.
