I hate to point this out to you, but, every online game in the entirety of the universe, is an unfinished game.
Even some games that aren't Multiplayer, and can be played offline, are unfinished. (updates, you know)
There is always something being added (how many expansions were added to WoW?) or tweaked.
And contrary to some people's feelings, balance is a necessary thing for the extended life of a game. Especially an MMO.
So, yeah. you might want to wait a few more decades or centuries before looking into playing CoH some more. Seeing as it's still unfinished.
Oh, and that other game you might want to play is also unfinished.
And that one too
and that one
...and that one as well.
