I really don't understand what your problem is. It's like you expect SE to just hand you everything you want because you paid $50 for this game, plus a monthly fee.
SE is adding things to THF, and you're upset because it's not enough, or what you expect? Sounds like they are making PD be sort of a Mighty Strikes kind of thing, but only when you're behind the mob. Seems like a good addition to me. Perhaps you wanted something different? Maybe a Job Ability that rains down fire, smoting all enemies in range is what you were looking for?
Every job has it's strengths and weaknesses. As a DRK, I do big damage, but have slow TP gain, and can barely solo an EP mob. Things that I can kill with ease as NIN would have me laying on my back as a DRK. It's one of the reasons I levelled another job, to see the game from another point of view, and so I can do things I could not before (lol, and get merits faster)
As a THF, you do less damage, but have faster TP gain, and can solo with no problems, as a bonus, you get better drops while soloing too. Guess that's not enough for you.
You need to stop focusing on the things you don't have, and appreciate the things you do have. That goes for RL too.
