Actually, i'd prefer the MOB's remain tough. Just increase the XP curve. Its kinda obsurd you have to group, and have to do tons of hard missions to get anywhere at higher levels. I mean, i get 7-20K xp per kill of yellow MOB's that i solo at my level. Considering it takes almost 9mil xp to level thats just not going to get me a level anytime this week.
I enjoy a good fight with a tough MOB(s), but i also would like to get rewarded properly for it.
