Cleric Weapon Skill Caps
 

Cleric weapon skills (1hb, 2hb) should progress at a rate of: (level + 1) * 4 with a max value of 175. Currently they appear to be following the format of level * 5.

The progress rate should be the same for druids and shaman. I haven't checked if they are or aren't. Druids share the cap of 175 for theirs (1hb, 2hb, 1hs), while I want to say that shaman actually could get to 200. I've never played a shaman to the point though where I'd be in a position to tell first hand.

Couldn't find a list of skill caps earlier than 2002, but OP seems to be correct:
