I don't see this as a problem. Triple-up heroic mobs are not meant to be soloed at all, in any terrain. Yes, some of us can do so later on. The fact that some classes can do so in their mid-30s is an exception, and that doesn't mean that we *should* also be able to do so. Sorry, I know it looks unfair, but heroic mobs are intended for groups anyway, regardless of dungeon or overland zone.
