Maths is racist.
Corrected the English there for you, a plural word when abbreviated does not become singular (despite what Americans think).
As I have said upkeep is fine, the old upkeep was far too low since it allowed me to run around with my fully heirloomed armour, which gives:
- 59 head armour
- 71 body armour
- 63 leg armour
Which is far too good armour, I would not wear that all the time even if upkeep allowed for it, since that amount of armour would make me lose skill. However many would not think in the same way as me and would run around in this all the time. So for the moment I think the upkeep is at the right amount, the only problem is for cavalry, but that is meant to be expensive since you are meant to have to balance your effectiveness with cost.
By the way, Mathematics is awesome, it gave you the thing you are using to connect to this website, it gave you electricity in your house. Quite simply the logic behind Mathematics is the reason you are not a caveman (without fire).
Also to further my point, the cost of repairs over time is completely independent of how long the rounds are, which some people seem to be saying here. The repairs apply per tick, not per round and so the amount at the end of the round is dependent on the round duration, but so is the amount of gold you gain.
