Turorial how to balance classes by yourself. The point of tutorial is: to balance all fighter classes and all mystic classes (for example: at your server fighters are too strong or too weak.. and the same with mystics). Every class has two "armor masteries" one for fighters and one for mystics, so we will need edit these skills and add for them bonuses.
All Fighters has Armor Mastery with 142 id: . All Mystics has Armor Mastery with 244 id: .

Now, we need go to data/stats/skills/ folder. And edit 0100-0199.xml and 0200-0299.xml. There we will find 142id and 244id skills (aka mystic and fighter armor mastery pasive skills). So we need edit them to balance classes by your own.

At fighter armor mastery (id: 142) we will see:
Code:
<skill id="142" levels="5" name="Armor Mastery">
##HERE WE WILL NEED TO INSERT FIRST LINE FROM BELOW.
  <table name="#pDef"> 9 11 12 13 14 </table>
  <table name="#rEvas"> 0 0 0 3 3 </table>
  <set name="power" val="0.0"/>
  <set name="target" val="TARGET_SELF"/>
  <set name="skillType" val="BUFF"/>
  <set name="operateType" val="OP_PASSIVE"/>
  <set name="castRange" val="-1"/>
  <set name="effectRange" val="-1"/>
  <for>
##AFTER <for> HERE WE WILL NEED INSERT SECOND LINE FROM BELOW (and do not put 2 <for> lines).
    <add order="0x40" stat="pDef" val="#pDef"/>
    <add order="0x40" stat="rEvas" val="#rEvas">
      <and>
        <using kind="Light"/>
        <not>
          <using kind="Heavy,Magic"/>
        </not>
      </and>
    </add>
  </for>
</skill>
At mystic armor mastery (id: 244) we will see:
Code:
<skill id="244" levels="3" name="Armor Mastery">
##HERE WE WILL NEED TO INSERT FIRST LINE FROM BELOW.
  <table name="#pDef"> 6.7 8.0 9.2 </table>
  <set name="power" val="0.0"/>
  <set name="target" val="TARGET_SELF"/>
  <set name="skillType" val="BUFF"/>
  <set name="operateType" val="OP_PASSIVE"/>
  <set name="castRange" val="-1"/>
  <set name="effectRange" val="-1"/>
  <for>
##AFTER <for> HERE WE WILL NEED INSERT SECOND LINE FROM BELOW (and do not put 2 <for> lines).
    <add order="0x40" stat="pDef" val="#pDef"/>
  </for>
</skill>

Now you should use one's own discretion for class balancing. Here is few possible classes stats boosts (or for belittle):

M.Atk. speed boost:
Code:
  <table name="#mAtkSpd"> 0 0 0 0 85 </table>
...
  <for>
    <add order="0x40" stat="mAtkSpd" val="#mAtkSpd"/>
85* number means the same as acument lv3.

P.Atk. speed boost:
Code:
  <table name="#pAtkSpd"> 0 0 0 0 85 </table>
...
  <for>
    <add order="0x40" stat="pAtkSpd" val="#pAtkSpd"/>
85* number means the same as haste lv2.

P.Def. boost:
Code:
  <table name="#pDef"> 0 0 0 0 85 </table>
...
  <for>
    <add order="0x40" stat="pDef" val="#pDef"/>
85* number means the same as shield lv3.

M.Def. boost:
Code:
  <table name="#mDef"> 0 0 0 0 85 </table>
...
  <for>
    <add order="0x40" stat="mDef" val="#mDef"/>
85* number means the same as magic barrier lv2.



P.Atk. boost:
Code:
  <table name="#pAtk"> 0 0 0 0 85 </table>
...
  <for>
    <add order="0x40" stat="pAtk" val="#pAtkf"/>
85* number means the same as might lv3.

M.Atk. boost:
Code:
  <table name="#mAtk"> 0 0 0 0 85 </table>
...
  <for>
    <add order="0x40" stat="mAtk" val="#mAtk"/>
85* number means the same as greater empower lv3.

Decrease/Increase dagger skill chance to hit the target:
Code:
  <table name="#Tab-blowRate"> 0 0 0 0 0.7 </table>
...
  <for>
    <add order="0x40" stat="blowRate" val="#Tab-blowRate"/>
[#Tab-] Means - if "tab-number" is 1.5 then "something stat" increases by 50%. If "tab-number" is below then 1, then "something stat" decreases (0.5= -50%) etc. :-X

And how it looks like edited.xml for Mystics (id:244):
Code:
<skill id="244" levels="3" name="Armor Mastery">
  <table name="#pDef"> 0 0 0 0 85 </table> #INCREASES p.def.
  <table name="#mAtk"> 0 0 0 0 85 </table> #INCREASES m.atk.
  <table name="#mAtkSpd"> 0 0 0 0 85 </table> #INCREASES m.atk spd.
  <set name="power" val="0.0"/>
  <set name="target" val="TARGET_SELF"/>
  <set name="skillType" val="BUFF"/>
  <set name="operateType" val="OP_PASSIVE"/>
  <set name="castRange" val="-1"/>
  <set name="effectRange" val="-1"/>
  <for>
    <add order="0x40" stat="pDef" val="#pDef"/> #NEW ADDED  p.def.
    <add order="0x40" stat="mAtk" val="#mAtk"/> #ADDED m.atk.
    <add order="0x40" stat="mAtkSpd" val="#mAtkSpd"/> #ADDED m.atk spd.
  </for>
</skill>
Attention! If there is old the same lines as new one's, we need delete old one's. For example: there cannot be two p.def lines. So we delete old one's:
Code:
  <table name="#pDef"> 6.7 8.0 9.2 </table>
Code:
   <add order="0x40" stat="pDef" val="#pDef"/>
The same thing we can do with fighters armor mastery .xml(id:142)...

#######################################

Also stats are possible can boosted by percents. Using something like that:
Code:
  <table name="#Tab-somethingStat"> 0 0 0 0 0.7 </table>
...
  <for>
    <add order="0x40" stat="somethingStat" val="#Tab-somethingStat"/>
