Why doesn't wrestling matches have a time limit anymore?

Evidently, Vince doesn't think it is needed anymore, but TNA does use a time limit, but it truly makes no difference, all matchs are pre-planed, so they know when it will end. TNA doesnt use a time limit anymore sighn,a true TNA fan TNA doesnt use a time limit anymore. Cool. It's great to see that at least one person is a TNA Fan.
