Hmm, I see what you mean, and see that I may have misunderstood Kael on this issue before. I'll check it out again when I'm back in the game.
Okay, I did some testing and number crunching and found out a few interesting things about terrain defense. The "actual odds" below were reported in the combat log.
Using goblins as the attackers and defenders (to make easy math) I set up 6 combats:
1) Grassland/Hills (+25% defense)
Attacker Promotions: Guerilla I (+40% att./def.)
Defender Promotions: None
Expected Odds: 1.40 vs. 1.25
Actual Odds: 1.00 vs 1.25
2) Plains/Hills (+25% defense)
Attacker Promotions: None
Defender Promotions: Shield of Faith (+10% str, +20% terrain defense - all types)
Expected Odds: 1.00 vs 1.55
Actual Odds: 1.00 vs 1.55
3) Grassland/Hills/Forest (+75% defense)
Attacker Promotions: Guerilla I (+40% att./def.), Woodsman I (+40% att./def.)
Defender Promotions: None
Expected Odds: 1.80 vs 1.75
Actual Odds:
4) Grassland/Hills/Forest (+75% defense)
Attacker Promotions: None
Defender Promotions: Shield of Faith (+10% str, +20% terrain defense - all types)
Expected Odds: 1.00 vs 2.05
Actual Odds: 1.00 vs 1.85
5) Plains
Attacker Promotions: None
Defender Promotions: Shield of Faith (+10% str, +20% terrain defense - all types)
Expected Odds: 1.00 vs 1.30
Actual Odds: 1.00 vs 1.30
6) Plains/Forest (+50% defense)
Attacker Promotions: Woodsman I
Defender Promotions: None
Expected Odds: 1.40 vs 1.50
Actual Odds: 1.00 vs 1.10
Conclusions Thus Far:
1) Since #2 and #5 were correct, it seems that Shield of Faith is working correctly at some times. However, it didn't work properly in trial #4. Perhaps it is only working properly for Plains at the moment (in addition to the Grassland failure in #4, the first time I noticed a problem with SoF was when defending on a forested desert hill).
More testing will be necessary to isolate the problem.
2) Guerilla I promotion appears to be completely ignored when attacking a hill, but more testing will be required to confirm this.
3) When an attacker with Woodsman I is attacking into a forest, the 40% benefit for the attacker is taken off the defender instead. It's great to see the game moving in the direction of accounting for an attacker's terrain promotions, but it's mathematically incorrect to use it on the defender's score. A 1.40 vs 1.00 situation does not have the same odds as a 1.00 vs 0.60 situation.
I apologise, Kael, for misunderstanding you on this issue earlier. I hope I now understand enough to provide useful feedback.
Time for bed.
