To the OP:
Let me first start off with saying I loved playing thf, but recently retired my thf (lvl70). Theres been many posts about thfs not getting the invites for parties on alla, and even on this thread. It is oh so oh so true...
I thought invites were very bad post 60... maybe 2/week if I'm lucky. Things are even worse post 70. I've seeked for nearly a month with nothing. I'm not going to get into the nitty gritty, but down to it, thf endgame is nothing but a TH biatch. You'll get invited to events only for your TH2/3/4. At first I didnt mind this, at least I was included in events... but when the exclusion comes to BCNM/ENM/Missions... you'll start feeling the reject.
As for farming and making money... you have tons of ways from this site alone. I can count on one hand how many times I've farmed with my thf for the sake of money (Quest items are a different story).
Check this thread:

The man has explained everything much better than I can, and he is oh so right...
Unless thf gains some skills to increase the invite rate... it would be very difficult hitting 75 (then losing 75 due sack pulls, etc).
OK im done, good luck!
