I believe there is a serious imbalance in the game, but it has little to do with FC's current or future patch releases.
Essentially, everything in AO is for sale - items, lootrights, tradeskills, buffs, even people. Some players are so unbelievably rich, that it is easy for them to obtain everything the game has to offer anytime they want it. Others, who are not as fortunate or business savy, have to struggle just to get a second-rate setup. Let's face it, if you don't have creds, AO can be very frustrating!
Best example is 150-174 Battlestation - some people have spent billions twinking their toons while many others run around in predator armor (or equivalent). Even a good PvPer cannot compensate with his skills for such a big difference in equipment. The twinked toon wins, plain and simple, as we can all see that happening over and over everyday.
What is true for pvp, is also true for pvm. The closer you get to 220, the harder the mobs will hit. The better (and more expensive) your setup, the more likely your survival. If you die a lot and can't keep up with the other players on your teams, you will soon find yourself camping lft - because nobody wants to team a gimp (of course, nobody will actually come out and say that openly, they just won't send an invite).
So, if I would have to give advice to a new player today it would be this:
Forget about the gameplay, forget about the different professions and races, forget about equipment, and especially forget about PvP - just make credits any way you can and don't stop until you have a few billions. Then start playing the game for real!
Keeping this in mind, any change to professions, nanos, perks, equipment and gameplay that FC has made (or will make) matters very little unless the economy gets a serious overhaul, because those with money will still completely dominate the rest.

P.S.
Before I get any flames, I'm not critizing anyone for having credits and using them (I do the same myself), I'm just trying to draw Funcom's attention to the bigger picture.
