Simply put, you spend even less than the other canta players do. The game is run by the cash shop now, and you are no longer one of those "elite players who can use money to boost their ego" Instead, now all 90 players in canta are , Legend, Double max OJ'd.
Also, if they 1 hit you, there's a good chance you're just not a good mage.
That aside, there currently was something that occured to game where certain classes lost damage, and others gained it.
I seriously doubt anyone's hitting you 7k lmfao. Best in canta are maybe 5k, and the average of two toons well geared versus each other is 2.5.
