Well, torparse is 100% accurate so your whole point is basically irrelevant. Also, in most boss fights I'm in the 1800-2100 range, so you must just not be very good, as well as the rest of your guild.
Based on your parses at TORParse.com, you're in the 1300 to 1800 DPS range on the SM boss fights; at least as recently as 11/14/12. That must have been Story Mode TFB as your group's TFB HM wipe-fest from 11/13/12 was painful to read, but shows that you're in the 1300-1600 range when the difficulty rises. That's not hard for a mara; and it's certainly not exceptional. Definitely understand how you'd be 'too busy' to share that kind of stuff.
