There are some people who reach much higher levels than the average because they have much more time to play this game. That's why their characters are OP. Players report class X is OP because the high level players of this class are OP. This results in a nerf of the class, for example by increasing the requirements on horses and crossbows, or nerfing arrow stun, two-handed lolstab and polearm turn rate. Casual players want to stay as strong as they used to be, and this is why they simply play more and reach higher levels, too.
On the one hand, developers try to discourage people to get high level characters by increasing the rewards of retiring after level 31 and making respecs super painful or unaffordable. On the other hand, they force players to make high level characters just to keep playing the way they used to after all these nerfs.
Devs, if you will not introduce a commonly reachable global maximum level where the exp gets frozen (which involves taking levels from characters who are higher and compensate the players with gold, loompoints, titles or whatever), make at least the fucking respecs cheaper. Otherwise, you are making people quit because they are frustrated about losing half of their efforts (be it exp-wise in the normal respec or loom-wise in the training lessons respec), or you are incubating the next generation of NEETs with a "nerf me to the ground if you like, I simply reach level 37 38 39 40... and stay as I am" attitude.
This mod is the popular Warband mod for a reason: It is insanely awesome! But that means that people will play it a damn lot, and you have some sort of responsibility towards the players who set themselves unrealistic goals and strive towards them, who spend a good share of their school/university/vacations from job/unemployed/retirement time in this mod just to get disappointed with the respecs in the end.
It is natural that everyone wants to try out other high level builds and classes once in a while, be it to make sure their initial decision was right, be it because they are annoyed of monotonous gameplay with the same character after grinding a nerf away, be it because they want to change their experience within the mod temporarily or permanently.
All we are asking for is some incremental humanity in this mod.
