Problem is than then 200 mp infatry will be able to dislodge garrisoned mgs on its own.
I would test moving the flamer to urban and merge with flame grenade that now would be available to RE.
Rifle-grenade could be move to rifle-company and moved to riflemen using the AT grenade animation, on could combine it with a "hit the dirt" type of ability.
That would probably fit the theme of both commander better.
Well I'd say that LT in a way can also solo garrisoned MGs. With his smoke + grenade. It is such a burden to convert a unit that you need for smoke/mine sweep to what amounts to just a flamethrower. I know OST and SOV have this too. But for them at least the enigeer is core so you don't have to get so far off track just to use a doctrinal ability...
I don't know if stacking more random abilities will really change the commander... I've also kind of had a change of mind concerning rifle. WP barrage + E8s makes for interesting plays. Still not a top commander but its ok.
