A lot really depends upon what my particular goals happen to be for any given character or phase of their career. Sometimes I just want the merits so I can buy a recipe or other item I want for said character, in which case, the fastest path for me is to run a TF on a lower difficulty. Some people may just want a badge that's associated with a TF. Other people find, especially for some of the older TFs, that the repeated "kill all enemies" or "click X glowies" are bothersome, and are really only interested in the final AV fight or if there's a unique location at the end. I always emphasize that communication is key; If you join someone else's TF, then you really should express how you feel and either remain or leave if you (dis)agree with the approach they're taking. If YOU want to start a TF using your criteria, then more power to you! I have no sympathy for you, if you are complaining but won't take charge to lead a TF yourself...
