Since alot of people only add as much WIS as they need for all their skills but continue to add CON the mage already has an advantage here since magic hurts more than physical. However it still depends on level, element, and stat distribution.

When I faced a Water guildmate in a pk I missed coma then they froze me and cast water thunder beating on me. However I survived then proceeded to defeat them in one hit, I got video footage if theres anyway I can post it here. Water is neutral vs. Wind however I did have a 10 level advantage on them. I burst with them regularly so was just a friendly pk ^_^
