Health gain from STR/IF is hardcoded and changing it requires more effort than it's worth.
Crpg has like 5000 players, right?
Let's assume that 1000 players are pretty active. If every player could donate just 10 euros,( to play other sh1tty games like world of warcraft you have to pay every month, while warband/crpg is free, once you have a cd key) the developers could get 10k euros , with this money it would be possible to hire someone who could help to code/program and stuff like that.
I don't want to sound disrespectful, I fully understand that coding/programming isn't easy and it requires devs free time. This is why the playerbase should start donating. Perhaps the developers can set a donation target, and specify what we would receive in return for it.
Really, donating isnt that expensive. Consider how much you spend if you go out and drink some beers, smoke cigarettes etc... Then consider how much time you spend with warband/crpg, and it's free... It is worth it to invest some euros in the development of this game IMO.
