So imo the Thac0 progression would be something like this. The most importan things are: basicalliy it is divided to warrior, priest, rogue, and spellcaster progression. The fighter (and hard codedly the barbarian) would receive 1 thac0 for every level, so to say their thac0 is equal with their level, even at 1st level.
Paladins, rangers, and monks should receive at every even numbered level, which is still good, but not completely dumb as in the original game, where it is equal for all warriors... And yeah the monk: they are priests, but without weapons, and specializations, and so on, they would have no chance to hit anyone. Thats why I intend to give them the same attack bonus like that of a paladin for instance.
Priest should receive 1 thac0 for every 3 levels, starting at 3rd level. This is also true to druids, as I don't see the reason why to cripple them (even with their good shapeshifting skills). A cleric is not better in the sense that 'they can hit better' but because of their equipment: better selection of weapons, and earlier, ability to wear even heavy armors, and large shields... etc...
Rouges, the thief and bard respectively, would have a similar progression like priests (1 thac0 for every 3 levels), but they should start gaining it earlier, which is cool. Thieves have the powerful backstab and cneak attack anyway, so it still good to somehow not overpower them with god-like thac0 too.
And finally the spellcasters, whom should really be unable to hit effectively. First and foremost because of their specialization in magic, and because some of their most powerful touch spells shouldn't be so easy to deliver.... They should gain only 1 thac0 for every 4 levels.
Finally, the maximum level for me is always 20. After it everybody slowes down to 25% of their earlier progression rate. This is reasonable I think, because at higher levels the enemy armor won't really become better (like after full plate +2 what else an enemy can wear??)
Ahh yeah and the table contains hypothetically level 40 for everyone... but obviously I would handicap SOME of the classes earlier, because of the XP cap... but save this for another topic.
