Vanguard already is one of the best doctrines that is used very commonly. Pushing what are essentially 4 special units/abilities (FHQ, Commandos, Commandos ATG and Commandos Mortar team) into one would be overkill. It's already a good deal package (FHQ and Commandos) as is.
If the Hq glider come with only commando, it will still is a thing and maybe. But once you add mg and at in, then it open up my question of why they are just the stock version.
Vanguard is indeed a strong Commander, and i think it strong even without commando and glider. There was feedback about merging glider and Hq glider, rifles commando, or outright replacing hq glider with other thing, i know nothing is easy to be done but if you go for some of those idea, it would bring something fresh.
I mean, if there are changes to be made, i hope it will be new, not something stock, or rather keep it old style.
Still, appreciate for the jobs, really.
