The approach I implemented for v106 is simple. Units with Blitz keep "ExtraAttacks" moves after attacking, unless they have the "Attacks Use 1 Move" promotion.
If I am interpreting correctly: "Attacks use 1 move move" promotion comes standard on chariot archer and UUs, camel archer, keshik, siege units, etc.
Naval units do not have this, so after an attack they only have 1 ExtraAttack movement point left?
That seems a little confusing; couldn't we have a system where the extra promotion was on the (naval) units with the rule-change?
Or better: get rid of blitz for naval units, but have a "doubleshot" promotion instead, that acts as blitz but leaves only 1 movement left after attacking?
I think the only situation where "bombardments-only" would make a difference is Mechanized Infantry. Introducing inconsistency between units with the same promotions would be too complicated, if just for the sake of one unit type with a specific promotion.
I don't understand what you are saying here. Mechanized infantry don't have bombardment.
Like Txurce, I would oppose this change if chariot archers (and other land units) with blitz could now no longer move after firing twice.
There is already a fundamental difference between the various horse archer units and the naval units, because the horse archer units already have move after attacking, so blitz just gives a second shot, while the naval units don't, so they end up getting both a second shot *and* move-after-attack from the same promotion.
