Hmmm, that's a tricky request to pull off, for a few reasons.
1.) Hard for it not to be a measuring contest
2.) TPS is incredibly variable depending on fight and moment in the fight (i.e. buffs, spikes of threat, etc)
3.) Threat is all about when it is applied, and only ever about how much is needed. If you can do 12k tps in the first 30 sec of the fight and only average 4k for the 2 min after that, that could be more than enough to cover you.
I'm curious to see where this goes, if it actually yields anything useful.
Osyras, my Blood DK (link above in my characters)
I average 6k-ish on typical boss fights according to parses (3-5% from healing)
On Omen I sample at 6 sec, and I've seen spikes as high as 15-18k with certain encounter buffs or when I get a longer chain of crits.
When I glance at it, my omen usually sits somewhere between 3.5k and 9k again depending on when I chain a few crits.
Since my gear has been switching over to Uld gear almost exclusively I have not had any issues with my dpsers riding my tail or pulling threat when they didn't do something stupid (like attack something I hadn't started threat on yet, like say after a threat drop).
Does that help? Heh
