Dude, this is no longer funny how much you can justify shit design.
I like the M5 Assault Group, post buffs. I liked the Recon Company AT Gun + Support Paratrooper airdrop too.
Unit bundles, if priced correctly, can be both viable and strategically interesting.
Sure, you could ditch the halftrack and just have Assault Guards, but then you'd just end up with another generic CQC unit. The price would
go up because unbundled Assault Guards are overpowered at a 270 MP 0 MU price point.
You'd just end up with another generic CQC squad. We've got loads of those.
If you dislike unit bundles on principle, fair enough, but the M5 bundle is well worth its price in its current state.
