Then the rest of the doctrine should be fixed along with well-deserved nerfs to canister round.
Its a doctrine with 2 kinds of reckon abilities and reckon, combat ineffective troops which at least have somewhat effective abilities.
As a cherry on top, you get ultra menpower heavy call-in with unreliable weapons on a faction that is extremely menpower heavy and punishes you for using it by forcing you to spend additional 80-120mp on AT gun or donate it to enemy.
I can't really think of a possible way to save the doctrine when M8 would be nerfed.
Just like dodge truck IS a mechanized doctrine, the same way M8 is a reckon doctrine. Everything outside of that single ability is a bad quality filler.
Basically, if not for M8, I would say that sierra together with lolcake designed the doctrine.
