See in Battletech, 'doing stuff' has two components when it comes to resupply, or repair, or customization (its really all the same thing). The "to hit" to do it and "the time" it takes to have it done.
If you have 40 minutes between two fights, and it takes 180 minutes to repair your armor, you dont get your armor repaired.
Now things like being in the field, being at a mobile base, being on a drop ship, or being at a factory, are going to change your "to hit" to do the thing, but hardly ever the "time" it takes to have it done.
The only thing really preventing you from turning mechs in Battletech into MWO Meta Machines is A.) There are already every mech you can think of and design you can think in the canon (megamek has like 2400 mechs) B.) your techs retire and cbills have to be earned.
The chance of you getting, and keeping, an elite tech that can take out your LRM20 and put in a c3 and more heat sinks and armor in a mobile field base in the blinding rain, is slim. Turning a Stalker into a defacto 6 LL Supernova, would take several months, and each month, that tech is going to roll to retire, or to find another job that doesnt have him doing completely insane complicated crap no one would ever do.
Just taking all a Firestarter A's medium lasers and replacing them with small pulse lasers and all the heat sinks to double, is the equivelant of having a custom AK47 made out of solid gold for you. Its that ridiculous.
But not that it cant be done.
But you also cant earn any money with your fancy awesome warmachine while it sits in a hangar bay for 5 months being turned into a JagerBomb.
