All that does is encourage the TurretWarriors rather than swarms . . . I prefer the bell curve (flat as it maybe) where units are stacked in the middle. For the case in example the turns would have been 1-1/1-2/1-. It had been a MM option as well IIRC though I have not messed the settings in a while and thus I am not sure it is available still.
Dunno, I think that's dependent on your group, though it DID keep the turretwarriors from flipping the table and storming off in my experience.
The bell curve idea looks kind of...complicated to get through, and kind of suggests a lot of arguing will result.
I'd say more than half the House Rules we used to use, were to eliminate arguments or streamline things. Stuff like pre-arranging "Bring your best 10K BV" blind matches (that is, where everyone is given a fixed BV plus or minus 10%, no other restrictions, and maps selected by random roll at the venue) were pretty common when I wasn't playing referee/GM for the other guys in a campaign. (For official events, I stuck those in Deathrider_6's hands as our local Commando rep.)
as the semi-official rep for 'dirtbag militias' I usually had to give somewhere since a majority of what I brought were conventional, non-'mech forces, while most of the other players were enamored with Clan units and customs. My 'give' was Front Loading initiative so that my gross fire supremacy and abusive use of good* canon tank designs didn't upset everyone with their custom icebox Clan 'mechs (fire supremacy because I outnumbered them from first initiative onward.)
(*Good being a relative term. Esp. under BMR(R), there's a lot of terrain you simply can't use Savannamissiles on.)
