I can tell you something about that.
1. Wizzard:
+huge dmg on Life Control
+can be invisible
+can see invisible
+fear/frost/burn/sleep
+quick multikilling machine
+can be subclass cleric for helping party/recorvery division
-lmao rotfl lol etc about his amount of hp
-quick death machine
-robe user + low hp = 'papper' armor + 1 hit k.o on him every pvp
-mobs 2++ lvls above him cant be death after 1 hit sometimes
-15 sec cooldown of pots
2. Chinese Nuker:
+great dmg
+not a bad armor
+can wear a shield and stay alive much longer than wizzard
+biggest defense than wizzard ever can have (no, i dont calc Bless Spell)
+burn/frost
+5 secs pots
-no subclass that can help you stay alive longer, but hey.. 5 sec pots...
-play start above 30 lvl
-need long farming to have good skills
3. Rouge:
+most versalite class ever: distance, h2h, can even be a less-class tanker
+big dmg
+stealth, destealth
+tag point (usefull aganist thiefes ;P)
+can have bard/cleric subclass (usually) that can help a lot in party and solo
+full rouge is the terrifing enemy on pvp... when away xbow when close - daggers
+CE and DD
+without subclass you dont require farming
-CE and DD... try kill your lvl gigant ^^ alone
-very low defenses (daggers with DD) or hy. defense and hp (xbow)
-can die easy when you are mobbed
-find good xbow or daggers on stall... GL ^^ if you dont have gold on SoX you have small chances to find one
- xbow can be borning... (45 lvl now but my fighting looks like:
