I'm a lvl 30 fighter right now and I'm slowly getting though the widowers nest. I'd like to lvl a bit faster though, any tips about were to go on my lvl and beyond?

Mutainous Malaise, it might be tough but great exp

Joining groups is the fastest, especially in HDOL. If solo, use flaming buddy.

Hmm let me write up a list for you

Fighters excel at taking down bosses and tougher opponents
heres a good list for your lvl and up
25-Do Hdol in a group, its great for fighter
30-40 Your gonna do ALOT of roc, if your in mutainous maliouse try not to get a large crowd, easy to die
40-50 Abbadons a little to tough right now, when your closer to 50, try shadow, use shadows embrace and GoS to lvl quickly
50-60 Now your sort of ready for abbadon, focus on Hdol and balzy
60-70 Balzy will be your best friend :)
70-80 Hmmm, Im not sure, probly hdol, bb, and when your closer to 80, rasputin( make sure there are no large crowds
80-100 U can do anything shadows embrace and above and have fun lvling and, doin whatever
