These are my ideas and a combination of ideas that I have read.
When each class reaches Dual 5:

You receive Dragon Slayer Title.

You receive 100 Points to add anywhere you would like.

NO SYMBOL UPGRADE
My ideas for balancing classes a little better:

Wizard -- Blood Light damage is reduced by distance (this will prevent random BLs from across the map)

Warrior -- Lightning Shock damage is reduced to normal damage (Original Lightning Shock)

Archer -- Cnverting Armor (AC Drop) keeps current damage (This will give archers that 'Range' logic that they need)

Thief -- Extreme damage is reduced (this will prevent Thief > Archer comparison since Thief get the Extra Defence)

Priest -- I can't honestly think of anything for Priest. Experienced players will not die to Life Drain At Dual 5. Priest are more of a support class, by using combination attacks. (Life Drain + EX) (Life Drain + BL) Etc.
After this, we can look at other options to give a variety of change between classes:

Fixing Combat Skills / Spells that are completely useless.

Fixing rares that are completely useless or don't currently work. (Critical, + Life, Weary, Etc.)

Making Candles, Potions, Food, Etc more useful.
Everyone has to keep an open mind. We are not trying to compare classes, but we are trying to give each class a role in PVP. This game required teamwork, whether you think it or not. The best way to balance the game is to compare 1 of each class VS 1 of each class as a team.
Hopefully GMs can think about this, and include a use for ARENA PVP in the future.
