Essentially... if you want to quit boxing, but kept coming back to Warcraft after a few weeks/months out of the game...
This is a strong incentive to stay out of the game.
So if you want to break out of MMOs, this is Blizzard's gift to you.

If you want to continue, with a PvP focus...
I believe you have battlegrounds in LotRO and RIFT, which are paid games likely similar pricing to Warcraft.

If you're into PvE, you have more choices.
You can continue with Warcraft, which is likely one of the better games in terms of panache and style... but one in which, non-boxer hate of boxers is something the developers are moving towards... so could easily also lose /Follow in LFR or even instances, if the whiners complain that the boxers are stealing their loot rolls etc...
You can move to any of the SOE games (EQ I, EQ II, Vangard), which are Free to Play... with the option of one-time investments (Station Cash, purchased with real cash), for whatever feature is included in the subscription version but not the FtP version.
Or you can move to a non-FtP game, where the company hasn't taken a heavy anti-boxer stance...
