Twin Terrors

On my level 24 duelist i obtained the passive trait Twin Terrors (75% increased chance to crit while dual wielding).
I opened my character profile to try and analyze this however my crit rating was only 7% main hand and 8.5% offhand.

I'm not sure if there is a different spot where this statistic is reflected or i if it is but it just didn't seem to be working for me.


STR:
1. Create a level 25 Duelist
2. Open up your passive talent tree.
3. On the right hand side of the tree (lower right side) there is an ability titled "Twin Terrors" Spend points to reach this.
4. Attack various monsters

Expected:
Landing critical hits often / increased crit portrayed in character profile / statistics.

Observed:
Did not see increased critical hit chance in my profile or while attacking.

if base crit chance is 10%

and you get a 75% bonus

===================
10 X .75 = 7.5
10 + 7.5 = 17.5
===================

your new crit chance is 17.5



if you then get a 50% bonus to crit
it will not be 50% of 17.5
it will be 50% of the base 10
