I love my Jugg, but I really liked the Geth (RIP Legion) and have always been obsessed with giant robos, AI and ANNs. Had I known they existed earlier, I'd have bought up all the Geth ME3 action figures.
I sort of figured the point of the Juggernaut was to soak up aggro because it can take it. Draw fire from softer players who can get squished, speared, stomped and smeared. I guess not being a rock star level gamer gives me a different outlook: I'm not going to be the guy on the top of the board often, so I may as well fill a support role that gets the team from Wave 1 to Wave 11 by minimizing casualties.
Like when I still played basketball, I wasn't the greatest scorer but was strong defensively and lead a couple of teams in rebounds. Worst team I ever played on was a summer league team where everyone tried to be the star.
When I play baseball, people think I can knock it out of the park but I can't so I play strategically (nothing like a well timed bunt to confuse the other team). I am not the greatest at ducking, rolling, grabbing cover, combo killing, sniping, etc - but I make a pretty good tank so that's what I do.
Mind you, the current build is sucking b*lls

. Sticking with 66066 from now on.
