I'm not disagreeing with anything said there. I'm saying that the cost for training at low levels is far too high. We're talking about ~100 (in a BTB economy which is much more restictive than a general morrowind economy) to go from 5 -> 6. That's quite expensive and the oppurtunity costs for spending that 100 even during the later period in the game is not worth it because money is so tight unless you need tho level that ability for its attribute because you don't have a major/minor with a primary attribute attached to it. Even then, its not worth it except to do so in ways that abuse the system by training the cheapest ones because you're not caring then about leveling the ability, but rather the attribute since the oppurtunity costs for leveling the attribute, as opposed to getting some way to fortify or bypass it, will never otherwise be worth the effort.

Just a possible conflict report: BTB - Settings.esp is overriding possible cell name changes by other mods (e.g. TR_map2.esm Marog cell), I think you'd better change it to a BTB - Settings.esm to be loaded right after Bloodmoon.esm so it will not override potential cell name changes by landmass mods
[EDIT]typo

In my (admittedly very little) experience, I haven't found the cost of paid training to be much in the way of excessive. I may go back and address it later if further testing/more feedback indicates that it's still a bit high.

IMO its just the lower end that needs tweaking. I find the costs for training my main skills (which I don't, but am using as a comparison) relatively decent for what level they are at (30-45).

It doesn't work that way, I'm afraid. Training costs are determined by a single GMST.

I do address this in the readme. As far as I'm aware, any conflict can be easily solved through load order adjustment.
