PlayerA: "hahah you're such a noob your so low level, you must have a life and have no time to play, probably busy with your gf and work, rl sucks lol you loser!"

PlayerB: "Yep, im the loser..."

The only sarcastic harrassment i can think of. The realistic one would be:

PlayerB: "Trust me this skill works you can do this and the mob does that"
PlayerA: "Stfu you dont even have rank 50 x or even a rank 50 at all so your opinion is incorrect".

It happens on the forums all the time "You're too low level to understand the game so you think its good but its not, you will soon find out when your high level".

i personally dont have a reason to be anon, but if others want it, fine by me, i just hope they dont lock it on lodestone, considering i run a website that exposes your levelling rates in the finest detail there is lol
