the one with better gear and scripts. ofc 99/99/80/80 16AP
Although 80 on subclasses make little difference I will agree with the Gear making a huge difference. However a good Feoh with almost as good of gear as the best geared Feoh that is bad would most likely win.
Necro/SH
the rest are pretty bad in comparison.
Except the rest aren't bad if you know how to use them :)
As for the topic, for your average player I would say the following:
mmm somehow ppl tend to overlook the ONLY feoh with actual pvp bonus ie; SOULHOUND. my matk may not be as high as SH/Necros, but my mcrits make up the difference and with +21% / 27% pvp damage, 3 UD's and AOE para well you get the ideal.
