hah but I meant they need core testers...lets say guys who will test beta and final patches in the stages of their production, before release on forums...or they have already few ppl for that...I mean for every patch, including betas they would need ppl who will pre test it...no?

Why Im telling this? Some of us have greater knwoledge of hardware, software optimisations and tunings. Some of us hav been beta testers in other (advanced) sims....we now how and what to test....
