If players pay the points for 5 tigers, they want all 5 tigers to turn up. They will be deeply unimpressed with any message saying that 2 of them broke down on the march and thus only 3 will appear.

If players want to upgrade their core troops, they will complain if the tiger is not offered on the fix/repair screen because of rarity rules. Same for any battle - if Joe Player wants to buy tigers then he wants them right now, not having to restart his game several times till the dice roll allows them to happen. "rarity rules" are not popular with end users.

And the same would happen for random mechanical breakdowns during play.

If such a system was in place - unless there was some way to turn it off in preferences then there would be howls of protest. 99.9999% of players would never, ever switch that preference button on in the first place.

The vanishingly small percentage of players who would use such a system would then complain that it does not fit their ideas of what should happen.

So it would merely be a wasted bit of complicated code to achieve nothing but annoyance.

Those of you who do so wish to self-impose some sort of "role playing" can roll dice or whatever solution suits them, as suggested by some posters above.

But rarity rules and breakdowns wont ever be happening.
