Cantha

Is this place 80% for level 20s?
Is there 15K armor sets in Cantha?
Do you fight the same mobs over and over again? (Kappa, Jade, mutalated people)?
Do you find some missions very difficult?
Just wondering because all I have seen is lvl 20s, and I dont like that, and I'm stuck on this 1 mission and all the gates are locked, so cant go anywhere, they need to chill out when making those missions, there like overkill, or winning tombs 3 times in a row, thats how hard they are.

Pretty much.
Yes. Kurzik, Luxon, and endgame 15K sets.
No more so than in Prophecies. As you move into different areas the enemy types change.
Some are harder than others.

Well in different area there are different enemies but once you get off of "noob island" mostly they are all for level 20's and if you contact me i might be able to help u on that mission
