It did play into that at the start, then there was a small problem that the setting made no sense when put under any scrutiny, a running theme that will persist throughout battletech's lore because very few writers understand how logistics work. And so because BT wanted to pride itself on being grounded sorta grimdark, the guys at FASA had to walk back a lot of the ideas of mechs being rare, introduce limited production of new mechs, but the circlejerk over the space roman empire (Star League/Terran Hegemony) remained.

(not that it matters or proves anything in a singleplayer game but) countless stalkers lie as smouldering wreckage in the wake of my MW5 Battlemaster squad with all rear armor reduced to 10 and all other armor maxed out. if nothing else the snail pace max speed makes piloting the stalker painful imo. i tried DPS builds for so long before just armormaxxing, now i literally never even lose a single point of structural limb damage on any mech any more, just armor damage to be cheaply repaired. if you play smart nothing will get behind you long enough to pierce the 10 armor points and the consistent quad M lasers + dual L arm MGs + SRM6 (sometimes SRM4 with more ammo) + occasional melee attack (i love that they added mech punching in a free update with their paid DLCs that introduced melee weapons) with plenty of ammo and heat sinks has been enough to shred enemy forces with much more tonnage than my unit. i even deploy overtonnage on easier missions and eat the deployment cost increase because i never get damaged enough to need expensive repairs or replacement weapons/ammo/mechs. as much as i like PPCs aesthetically and conceptually, every time i tried a mech with a PPC i was overheating constantly or agonizing over lethargic cooldowns during climactic fights, unless i removed most armor and weapons to put in heat sinks. the cooldown for PPCs is already so slow without having to take a 30 second break every time i get into a real fight. larger autocannons i kept running out of ammo and never had enough weight for the armor, ammo, weapons, and heat sinks i needed, and unless you use an ultra autocannon and risk jamming it, they have cooldowns just about as slow as the PPC, and are very unsatisfying to use. i wish they were all automatic like real-world autocannons, i hate the slow tank-cannon style loading times. the Banshee worked out decently but they are just so much uglier than a Battlemaster imo and not that much less time to kill against enemy mechs. I think i do better with beam weapons usually in MW5, i can kind of guide the aim-assist to specifically target the cockpit window for insta-kills with lasers, i'm often surprised when nothing but my chainfiring quad short burst M Lasers gets a bizarrely fast kill on an enemy Awesome or Mauler or Atlas, while with autocannons or LRMs i can never seem to consistently hit the same place, with the damage getting spread around multiple body parts and sets of armor and HP.

edit: also it might be 'cheating' but i play with the optional FPS-style controls instead of the default classic tank style controls, it doesn't make sense to me to have a bipedal robot that can't easily strafe and handles identically to a very tall tank. idk exactly how that might break the default enemy AI, it definitely makes juking back and forth to avoid damage easier tho.
