I think it is an interactioon of effects that gives steppe armies an advantage.rbodleyscott wrote:There is no question of the terrain rules being designed as a blunt instrument to favour Mongols (et al). On the contrary, it is designed to reflect the sort of terrain seen in Ancient/Medieval pitched battles.
At the risk of repeating myself, Mongols don't need "an arbitrary terrain selection" to be effective. They are able to cope with pretty much any terrain selection. The same is not so true of MF-predominant armies, but that reflects history.
They have lots of LH and Cav, so have a high PBI, consequently they get to choose terrain more often.
They have lots of LH and Cav, so want low terrain density.
Steppe has a low terrain density, and doesn't work well with the terrain choice system.
The problem with steppe is that a player that doesn't want terrain doesn't do it by picking pieces of Open ground, but by picking 4 minimum pieces, using up 5 of the 8 non open terrain pieces - this is the only terrain type where the first player can pick all the rough and difficult terrain to deny it to their opponent. I suspect the real issue here is that a player can negate a terrain piece by picking it and making it minimum size. The solution is to change the minimum sizes. For a normal piece it should be able to entirely contain a 4x9, and/or a 6x6. For a large piece the sizes should be 5x12 and/or 8x8. I suggest larger sizes for larger pieces to make sure they are larger, and not just a minumum size piece stretched out to just be large.
The other problem is a consequence of FoG not modelling where and why the battle is taking place, but basing the terrain for an army on its homeland, not where it fought. In many cases steppe armies effectively won the PBI, but couldn't choose steppe as they were invading another nation, and there was no steppe near enough.
The question is did the Mongols fight on the steppes, other than in a civil war, sufficiently often to justify it being on their terrain list, other that as a special case?
One way to try to model the why and where without changing the army lists is:
The side that wins the PBI gets the option to invade the other side. If it does so it chooses terrain from the other army's list.
Otherwise the other army may choose to invade. If it does so re-reoll PBI, and the side that wins this chooses terrain from the first army's list.
Otherwise the first army gets a second option to invade. If it does so re-roll PBI, and the side that wins this chooses terrain from the second army's list.
If neither army chooses to invade the game is a draw (10:10)
If the PBI re-roll is a tie then the first army keeps the PBI.
If any PBI roll was a tie the army with the initiative can choose terrain from either army's list.
Ties mean the encounter happens close to the border so that the full choice is available.
