Not necessarily, Mitchplate. Consider that they are already working with some rough build rules and are continuing to fine tune them to aim for balanced Prime through E variants. Once they start on mechlab they would then have a solid foundation of what a balanced load out is versus what isn't when determining final Weapon Pod size and armor values on said pods for given variants. Restrictions on the size of pods for the arms of Clan Heavy Mechs, for example.
Now, on the flip side I do believe the balance issues can and will be discovered far more quickly by the beta testers if they had access to build rules or a mechlab, but we don't, so all the theory-warrioring in the world (which I am quite guilty of) will not help us at this time. Until then it is our duty as beta testers to continue testing the crap out of what the devs give us to play with.
I'm in no hurry to see Mechlab and find MWLL to be a more enjoyable multi-player experience (even with some of the ridiculous variants) than any previous Mechwarrior game before it. I say leave the customization to CBT skunkwerks and heavy metal pros and make a balanced game without giving the devs ulcers in the process.
