In the example I was talking about it wasnt 6 elite mechs versus 40, it was 4 PC mechs in a heavy lance 205-280. Its cause 1 each of foot, motorized, jump, apc, field gun is 600 BV for 5 units, so a battalion is 2k for 15 units, followed by an armored gun company of scorpion types for 12 units at 4k. So 2 infantry battalions and a armored gun support company is 8k BV. Since I randomly rolled into an infantry force on the RAT table, its not like I went out of my way to spam cheap stuff, it was fairly rolled up as opfor, all i did is change some of the oddball units to make fewer types of units, so like all the foot troops became 1 type instead of a flamer/srm/laser.
Now, yeah for 8k you could also take 6 Manticore instead of 42 combined arms things, but the point is that infantry formations do exist, and BSP make that scenario so much more fun to play now versus then.
As long as you use like 2 TW hero tanks for the 'cool guys', counting as part of the unit count limits as mechs, the rest of the force in ancillary BSP has been a godsend for playing combined arms. Even elementals work the same. The BSP elementals are fodder, but the TW elementals in a clan force are the 'frontline' troops eligible for bloodnames/xp/pilot upgrades, and take a spot as a mech for force construction guidelines.
You can address the issues with BV2 without grafting a system onto the game that was probably developed for a completely different game that never got finished enough to publish.
Your BV example, for example, presumes players have that much money to spend on minis, or that much interest in making their own proxies, plus sheets, plus lists, and doing all the math when they aren't doing it on Megamek.
admittedly, there ARE autists that dedicated in the community. I remember a period around 2002-2006 where I was buying blisters of whatever was on Gary's shelf and inhaling paint fumes in the apartment kitchen for hours, mixing in greenstuff and model train terrain and moss for grass. I gave most of those to friends as gifts, if they were any good, and kept the failures. (They're still around here somewhere).
But after a while, it became a burden instead of a pleasure doing that, and after your fiftieth little tiny microscopic Davion Army Man it becomes largely not much fun at all.
Not even adding an n-scale Jeep with a homebuilt crew served and cutting one of them up to be the driver.
It just gets...eh.
Even doing it with software, the amount of paper you end up lugging around starts to rival the sourcebooks, keeping track of that shit gets annoying too.
the mismatch you're theorizing? becomes too much of a pain in the ass to assemble and formulate, and that's before you start with the record-keeping, because you have to haul all that shit to your game venue most of the time, and if I wanted that much inconvenience, I'd just break down and play Warhammer.
Keep in mind also, while we've all heard the apocryphal tales of the Majestic overpower of the Savannahmaster Swarm, I've seen players try it, and I've tried it, and it rarely works that way in practice.
what tends to happen more often, is an Equal BV of level 1 'mechs will stride off the map with some damage, leaving the hovercraft in ruins.
or as salvage. They're actually significantly better in smaller numbers attached to REAL UNITS that can do damage, or, y'know, can operate in areas on the map that aren't flat and featureless.
Could they be simpler? You BET they can! Under BMR(r) they WERE simpler-the sheets, the rolling, simpler. This was what was being 'fixed' with the vehicle rules introduced in Total Warfare-they made them more complex.
Now we've got BSP-which is supposed to 'fix' them by simplifiying things...and adding an entirely different set of rules that don't fit in order to do it.
It's almost overcompensation. BMR tanks died a lot more easily, sure-they had things that killed them outright (fire, inferno strikes, heat causing weapons of all sorts) and there were literally units that weren't worth the BV they had to cost because of how BV1 (and 2) are calculated. BUT...you could still build tactics within their limitations, because those limitations were not arbitrary luck rolls. Nor were the counters.
But it was consistent. Two tanks of the same model on the mapboard worked by the same rules, not "One set of rules for this one, and an entirely different set for that one, but they're both Manticores".
Do you see the problem with that?
this, is not how you ease a new player into something. It's how you punish your friend who likes Hell's Horses (Or dirtbag militias) for being a [badword] and not using a proper star of Battlemechs and proper duelling rules.
