I never said that you have to have population, just superior firepower. Medics and engineers act as force multipliers by keeping people in action. Attrition means is about killing your opponent to the point where it drains them. Bio-labs are about keeping as many people in the fight as often as possible to maintain superior firepower. Basically, its two walls of bullets trying to push each other back. Basically kind of like this.
Some outfits have very high standards, and good for them. I just don't want this to be a community that tears people down for not having good stats. That's toxic. Community is the only thing keeping some people in this game. If the community goes sour, then kiss planetside goodbye.
