The premise was people won't use it, so why include it. Are you saying people would not use the Ref card?
I'm saying a reinforcement card is redundant on French brawl since there are extra armies per extra territories which encourage expansion. The reason why reinf cards are added on most templates, is to encourage expansion, and that purpose is being served in a different way here.
Nobody can give a reason not to have advanced attack options (aside from most won't use them), yet there are reasons to have them.
Clearly we have different ideas on what a good template must be, so I won't press further.
