Reply to OP:
People are going the war/pally/cleric/ranger base team setup because its the most efficient. That doesn't mean its the only choice. You also have to take into consideration that Hunter is by no means done doing tweaks to the various classes. (he just recently tweaked Zerkers epics weapon delay)
Regarding your Wizard, keep at it. Lots of cloth rots in qvic/tacvi/t1/etc. Other than the odd person gearing up an alt, there is almost always cloth rotting on my kills so i can imagine what its like for everyone else.
If you are going to play classes other than the ones considered "bread and butter" and you don't want to box my advice is make the effort to either join a guild or form a guild. Try find like minded people who want to play things like zerkers, rogues, etc. A full group of "alternate" classes will do fine if you have sufficient survivability.
Do what you want to do and have fun. No one said conform to what everyone else is doing. Play and have fun, if its not any fun its not worth doing.
OP: Your fucked dude.
Hunter once stated that he thought it was bullshit players only used war/clr and war/clr/rng and that other classes should be used as well.
Since that time Paladins got fixed and its now war/clr/pal/rng however most other classes got ignored or got bent over and stuck in the ass hard.
Blame it on the retards that played like dicks and crashed zones on people on purpose. <Final Dream>, <China> and shit spring to mind.
However its not that hard of a game to 'beat' using oddball classes. I mean shit look at that ugly gnome gnaughty he played wack classes for a very long time and was cool to chill with.
If you really like the combo you have atm dont worry about it, play those classes and just have fun. At some point in time you either have a good rep and get hooked up or you have made friends and gotten hooked up.
