Now in all my years of gaming I always though the point of a beta was to play/demo a game to see if theres any glitches/bugs/ etc etc that need to be fixed and give feedback to the devs so they can take care of it before final release?
If that is the case then what purpose does it serve to have a beta played on a build thats "a few months old" when the current build might already have all the issues in the old build fixed already?.
Thus to me beta testing on a build thats anything other than the most recent build just sounds completely dumb to me, though if anyone can explain to me how testing on an old build makes sense then please do.
