I am walrus, palatro did it for a gen and is now a thrower. maple whisky is a throwing lancer, bitchyouaint is a 2her currently. Not trying to downplay it. You said Semenstorm comes on with 10 maulers, and i corrected you. Its 2 maybe 3 maulers from semenstorm. Fluxy is the only other notable long mauler that i can think of off the top of my head that isn't in semenstorm. I have never even remotely seen 10 long maulers on 1 team, 5 maybe, but you know that is few and far between.
On the topic of skill, i can just as easy say that what you do, 1h with shield is skillless. Ive shielder well over 10 gens in CRPG. I challenge you to try out this build and pull a decent score. I promise you, it is significantly easier to score well with a shield, long pointy stick, or a longsword.
Can you honestly tell me who is noteworthy with a crushthrough weapon on NA other than a couple semenstorm guys and fluxy_mb? Not to put anyone down, but nobody really stands out besides maybe 4 people. Players always flock to the easiest way to play games, which is why you see so many crossbows, throwers, longsworders and spearmen. What do you not see a lot of? Mauls, because 9/10 people who pick one up suck ass with them.
