Got a few ideas, let me know what you think.

Ninjas:

Katanas can FB, like backswords SS.

Unique weapon (eg mana draining katana)

Transform skill (eg "dragon" like Tao's fish but for ninjas)

Fire Tao:

Better pure skills (dodge sucks)

Attack which damages over time

Magic attack boosting spell

Water Tao:

HP increasing spell (eg 2% then 4% then 6% and so on)

Better buffs

Effect Reversal (eg stop fog, poison blade)

Archers:

Lv120 (or 130) arrows (eg 1500 to a pack)

Special arrow packs bigger (not 1 per pack. that sucks)

Better pure skill

Warriors:

Defense increase (shield skill/effect)

Attack increase

Good pure skill

Trojans:

Cyclone adds to attack not just speed (eg 2x atk)

Herc that stunns mobs in a certain area

Pure's get def bonus

Obviously I have tried to make being pure more appealing.

Also I think you should be able to attack from mounts. Upgrades as a 1st/2nd RB are cheaper then non RB. Have an attack bonus as a 2nd RB.

Oh yea and maybe make MC a bit bigger, i cant find a spawn in reds that hasn't got 2 other players in as well =/

Hope TQ listens to this and replies, after all if we like the game more we will play more and buy more stuff =)
