Hmmmmm very tough question. Lets put it this way: I have a great set of composite armor. I have a ryyk blade 88-203 dmg and a 2.2 attack (im a fencer). I can take down a rougue fambaa, giant peko peko, and stay alive against a krayt dragon for 1 minute!(im not a master) i just have footwork I.
My friend is a pike man. No offense to him but he really sux ace if he dosent have a creature out. but yet again his weapon isnt that great.i can only talk for fencer.
Here is what a fencer is supposed to be: a really good PVP'er, fast attacks, low HAM cost(compared to most), and a really good dodger. With center of being i only get hit about 1/2 the time when its up. In PvP centerofbeing kix ace.
Pikeman. . . . . . the damage over time master. Honestly, you will **** everyone off in PvP. They will be like walking to a med center and start twitching lol. Its really up to you both are good but i got a feeling the are gonna revamp fencer or atleast give it a knockdown attack.
