Many players wonders what the troop-loss will be in a given level of the BG’s.
My experience with the BG’s ( i do not do defensive BG’s though I think that defence is booring) is that it is rather expensive due to the loss of troops you are having compared to what you get back when you have done the quest.
As this loss for sure, ALLWAYS will be there, then what is the plus…?
Most of the time, you will get troops that you arent capable of in your castle.. ( occults or bestiary) or you would use a long time to recruit.
I concider BG’s as an “investment”, in that matter that the damage you do to the cave or althar you are working on, does not re-build. It will stay at exactly the same damaged level (slight, cripling, moderat, or critical loss) even if you stop hammering them for weeks before you continues again. The loss is naturally more remarkable if you have decided to do one level in one attack.
What I will recommend, is that you brew up about 50 or 100 pikes a day ( tune this after your level at castle) and use these AND the Wraiths. They are free, why not use them to earn something extra!?
The point is that the troopcount you use to work down the count of occults with, shouldnt be affecting very much on your daily play. And BE patient, the price WILL come to you in the end. Rushing will only lead you to loss that will affect your game more than it should.
Ive figured out that the increase of the number of occults in a cave is between 20 and 25 % up per level you raise. If the occult count is for example a total of… lets say 100 at lvl 10, then you might concider that it should be about 125 at lvl 11, and 155-160 at lvl 12, and thereby approx. 200 level 13, 240 at 14, 310 at lvl 15, about 390 at lvl 16, etc etc.
Ive done lvl 38, and I might tell you that it is a pretty tough nut to crack.
Anyway, good luck with the fights in the battlegrounds. remember, take your time, no one is taking them away from you!
