Okay, I've made a fast check, and one thing I can already give out is a fix for skills:
Code:
UPDATE dbo.SkillResource
SET critical_bonus = 0
where id <> 45321 and id <>45323 and id <> 2074 and id <> 47016
GO
At the moment - and seems most of 9.4 Server didn't fix that - EACH SKILL has a safe 26995% critical chance...
Was really funny to realize that, and to see that it did not attract attention, since most of server have much buffs which increase the critical rate.
It had no effect on autohits, but classes like mages had a 100% critical chance even with level 10 first Job. xD
With that query there are only 4 skills left with 100% critchance (1 skill of m.genie,p.genie,staged nightmare skill and that one hide-skill of assassin), which are also stated in their tooltip as 100%-critchance-skill.
