I encountered the exact same issue. Another scenario is if a unit is a conditional battleline only if X is your general. My friend believes that once X is removed, it is no longer the general and the units would lose their battleline role. I want to dissagree as you paid for the cost of a battleline and therefor they are a battleline, period. There are no answers to this in the book nor anything in the FAQ as this has only started to be an issue in GHB20. There is no rule that says that a unit can lose it's battlefield role so that is why I interpret it as they keep their role throughout the entire game. As for pink horrors and ardboyz, I believe that the battleline restrictions set upon them are only to be followed in the list building phase and once you buy them in as a battleline, they are a battleline until the unit is wiped. I believe it to be that way as it would be consistent with the "there are no rules that say a unit can lose their role during the battle". HOWEVER, the contradictor would be, once again, pink horrors. They count as a wizard when they are 9+ pinks but are not wizards if they are less. With that said I do believe that this is an in-game mechanic whilst the previous restrictions are for the list building phase. Concluding, I believe that once you buy in a unit as a battleline, they remain as a battleline unless stated clearly that a unit loses its role once Y is no longer met during the game. This is me opinion but until GW releases a FAQ adressing this, there is no right or wrong. Until then, I suggest avoiding scenarios where this can play a role.

Just for clarification, if the Dawn riders charged, they can still pile in 3" even if they wont be able to reach the blightkings (but can only attack if they reach them). If they did not charge then they can only pile in if they are still within 3" of the blightkings.

If you are playing pitched battle then on page 73 of GHB20 it states "You can purchase up to 1 extra command point for 50 points." Same thing is stated in meeting engagement so you can only purchase 1 command point in total!
