Afer 2 weeks camping this charm for the decent AC only to find it is useless at level 60, I'm a little disappointed.
As a level 60 Paladin I have all available weapon skills maxed. 1hs, 1hb, 2hs, 2hb, Archery and Piercing. The current skill cap at level 60 is 260 for weapons and 230 for archery. My charm is only showing 10% effect though.
With the changes made to skill maximums since this charm came out, this charm has lost a lot of its allure for anyone not able to reach the skill maximum (as opposed to the cap for your level).
I don't even know what the actual maximum skill level is these days, but if you have to be level 65 or higher to get full stats from this charm then it's not worth as much as it used to.
I would rather SOE change the working of this charm to gain power as your weapon skills increase. All usable classes can use the same weapon types, except perhaps Throwing, so they could base charm effect on combined skill number just like the charms that are based on your AGI+DEX and other stat based charms.
