[Addon] XP tracking for entire group?

I was looking into an addon that tracks xp/rep, and I got to thinking, there should be a Multibox one! I have the experience bar on my PitBull frames from the Multiboxer v2 addon, but I'd like to have one that has group wide xp/hr, so I can see if one person is missing out (dying first, missing quests, etc) I have some catching up to do on my Tankadin, and killing mobs his lvl nets different xp per kill than the other higher lvl chars, so keeping them together isn't gonna even it out. I'm doing gather quests on him, and not the alts, to make up the difference, but if I could see if the xp/hr is higher on him as a result, I can know if my efforts are fruitful or not.

Does something like this exist? If not, it should definately be a feature request.

Sorry if you already know, but you can have pally be out of the group and only have the alts heal him, and he will get full exp instead of sharing it. If they help kill, some exp goes away. If they are in the group (even if they don't help), exp get shared. And if you skip to higher level stuff that you normally can't handle, then it goes faster, since the mobs are worth more and the quests are worth more also. I might recommend like +4 +5 mobs. Depends on your group setup.

Yeah, I know about tagging, but it seems like more coordination. I also have all my macros set to [target=party1target] so i'd have to tag with the pally out of grp then use another char to target with the group. I think I will just carebear a third pally, to use as a carebear for my 21 pally... so many pallys lol (they've always been my favorate, but lacking in dps, which is why I got into boxing anyway)

I have sort of the inverse problem. My tankadin is the big dog in my group, which works out very well. My dps are 2 levels lower (for reasons mentioned several times) but now they don't get the same xp for mobs and have no chance to catch up. At this low level (20s currently) and low gear available my dps (mage and lock) get a 90% threat warning from Omen sometimes :/ Even being 2 levels down. This is a pain when starting a new instance, as far as quests go. I just hand level my lowbies a bit when I get a MB headache :P Something you might now have thought, cuz' it may be stupid, but I have 2 whole sets of macros in all of my toons macro list. That way I can use 2, 3 or 4 toons if I want just by swapping macros around. I keep the same type macros (i.e. follow, nuke, and heal) in the same place as my normal keys but this lets me pick different leaders. I did this initially because I have my gatherers as different toons than my main and I can't figure out how to see the nodes on my main toon's map :P
