Limitanei MOD, of interest ... or not.

[PvK]

Ok. Again, I think a mod to increase such would be interesting and worthwhile, especially if you and others would like it to be that way. Which is me not saying much, since that's what modding is for.

As for the unmodded game, I think it's ok and by design, considering the following points.

* Level 25-30 is supposed to be generally a large commitment to defense, and not the usual thing to spend money on, except in special cases.

* It can be worth it if it is an important province which needs a tough defense, not because the defense can necessarily fight off a really tough attack by itself, but because it can make a tough defending army much tougher because it uses no food, can lose all its men and regenerate for the next attack, etc. When successfully defending combined with real units with complementary orders, suddenly the defense investment can really pay off.

* Arco and especially Pythium are considered some of the strongest nations, so it's good they have some weakness. I don't have a lot of sympathy for them not being able to have great maintenance-and-food-free regenerating defenses as well.

* For Ulm on the other hand, going from 25-29 takes you from 5 HI that will run out in front of the 19 arbalests, to 9 HI, which is much more likely to stop an attacking army, or hold them off long enough for another 19-38 arbalest shots to launch.

* Once it starts getting expensive to add defense, you can add a few real units to defend, who can patrol, and can have special orders that take into account the large free regenerating defense in the center.

* Defense can also be raised in any friendly province without any construction time.

* Defense never fights enemy defenses - it fights attacking armies and spells - so balance should be considered in that light, as well. For example, attack/summon spells like Hordes From Hell can overrun a certain level of defense; so if you increase defense, you're also reducing the usefulness of spells of that type.

Those are reasons I think the settings seem to be good in the unmodded game. I'd still try out and probably enjoy your mod, though I recommend keeping Arco and Pythium defense weaker than that of weaker nations, unless you weaken them in other ways, since they're already considered to be so strong (especially Pythium - ouch!).
