Geez, I almost feel like spamming a forum
BUT, there are two more solved, one likely solved but also one more riddle:
First the good news:
One Handed Clubber (Hit): 2% Agility, 3% Strength (confirmed by 2 Avatars)
Two Handed Clubber (Hit): 2% Agility, 4% Strength (confirmed by 2 Avatars)
Assuming that MC contributes 9% to Knifefighter (Hit):
Knifefighter (Hit): 2% Agility, 3% Strength (confirmed by 2 Avatars)
Then, assuming that MC contributes 12% to Whipper (Hit):
Whipper (Hit): 1% Agility, 3% Strength (kind of on the border)
One I cannot solve (MC combat 12%):
Brawler (Hit):
It comes out at 3.1% Strength 1.6% Agility which does not really fit into the system. 3%/2% does not fit, so I guess one of the contributing skills is off by a percent or maybe even half a % (one solution could be CR 3.5% instead of the proven-from-chipping 3%, Strength 3%, Agi 1%, but that is really guessing).
It appears from my disciple (has only used Shortblade, therefore all except Knife is only affected by secondary and general skills), that Brawler (Hit) is a bit different than the rest (0.25 profession levels vs. 0.234 for the rest of the melee ones).
Here's the screenie:

No more spamming today -- I need some confirmations from 3rd Avatars before I update the first post.
