It's not THAT easy-mode UNLESS you have your uber 1v1 fighting weapon with you that you can use at will. It was kind of ridiculous when I went in with my 1h+shield, switched to my maul to kill a shielder battling someone, then just switched back.
This won't affect dedicated users that enjoy the weapon. You can still find good weapons on the ground from defeated foes, too. I believe that you should just drop the maul.
I will be (ab)using this tactic on my 1 wpf 2h character so people will understand, not just whine and do nothing.
So you made this thread because of what you experienced once, rather than what you've tested for several hours/days? You found an "advantage" (Using a great maul against baddies that don't realize they could just spam you) but didn't take a look at any disadvantages. You're a good 1her but using a great maul with 1 wpf is just asking to get spammed down. 80 speed 1 wpf is brutal, it's hard enough to not get spammed even at 100 effective wpf.
I use a 2h/1h hybrid build except 131 2h wpf and 89 1h wpf in heavy armor(26 weight in total). Nearly every 1her, regardless of their build, is going to be fast enough to spam through any of your swings, even if you turn into your swings. Which is interesting because most people seem to think the great maul is an anti-shielder weapon. I'd rather fight a great maul guy with a short fast weapon, than a long slow weapon; of course, that's the offensive method to doing it. Alternatively, you could go the defensive, high athletics, long range weapon route and just back-pedal spam.
When I spawn with my great maul + niuweidao, I don't use the maul against "skilled" 1hers or fast 2h/pole guys (Unless I'm being stubborn, in which case I get penalized for it quite a bit). My point is, the only thing a great maul, by itself(not paired with say, a long spearman) is good for, is sieges(only at certain key points) and quickly getting rid of unskilled players. Maybe with a level 34 21/21 build you'd be fast enough to neutralize your disadvantages by taking a second (and significantly longer range) weapon, but is this really a situation that should be considered?
