I am just getting round to reading Blood of Baal and I am utterly baffled by the rules for the new 'Delaying Action' mission. I feel like I must have overlooked something because it makes no sense to me whatsoever.
In the mission's defence, it will never get used. One player needs a Blood Angels force that is split evenly between phobos troops and jump pack guys. The other player needs a Tyranid force that is 1.5 times as large. Those requirements are so absurdly specific that no one will even attempt to play this.
From what I can tell, the idea is that the Tyranid army starts on the right side of the table. The Blood Angels are supposed to put their phobos troops in a deployment zone in the middle of the table, with the jump pack troops in reserve. They are not allowed to bring in their reserves until turn four, unless they can control an astropathic beacon that is situated on the left side of the table. Whoever has the most power level on the table at the end of the random-length game wins. The intended premise of the mission would therefore seem to be that the Blood Angels player needs to rush their units from the middle of the table to the left side to allow them to call in the rest of their army. The Tyranids need to stop them from doing that, or at least to soften them up enough that the jump troops can't make a difference.
However, I see several glaring problems with this:
1: The Blood Angels player begins the game with phobos units, which typically don't need to start in the deployment zone. They can just deploy them on top of the beacon, allowing the Blood Angels to bring in all their troops right away.
2: The Tyranids get to deploy their entire army at the start of the game. The mission has rules for bringing in Tyranid reserves, and even a special stratagem that allows their reserves to come on from the top and bottom table edges. However, the rules for deployment say nothing that compels the Tyranid player to place units in reserve. Indeed, they couldn't place anything in reserve even if they wanted to, because 8th edition does not allow reserves by default and the mission rules say nothing to contradict this.
3: The Blood Angels start with 0.5 of an army on the board. The Tyranids start with 1.5 of an army on the board. If we house rule that the phobos cannot deploy on top of the beacon then they have no chance.
4: Even if the Blood Angels cheat by deploying their whole army on the first turn they are still at a 1:1.5 disadvantage and are very likely to lose.
It seems to me that the only mission in this book is completely broken, with the only saving grace being that most people will never have an appropriate collection of models to even try it. Or am I missing something here?
