+1 (pavise only) or +2 MA (bunus+pavise) have the same effect, they take the same amount of hits from both knights/paladins and hussars, it would be better only vs pikes and camels, which are units that are already bad vs xbows.
Yes more MA it help occasionally here and there, but I would prefer more PA (+1 from the bonus and +1 from pavise) and maybe sacrifice the MA for extend the bonus to skirms (they would receive only the +1 from the bonus, not the +1 from pavise).
Yes that’s what I was proposing, however anything would still be a huge step forward, and better than nothing.
Yes but if you improve the unit (xbow) with another bonus it would become a very good tech.
Basically you would get half bonus for free, and half for a price, but overall it would be a very good bonus.
