There's a lot of annoying shit in the game that is just blatantly pub stomp level of power, but ultimately falls flat against coordination. Torbjorn turret is one of them.
Unfortunately, this is fucking pub central right now, with right click hero McCrees left and right, Widowmaker firing lines, and always charge never shield Reinharts everywhere. So pick your pubstar and wreck the masses, because goobies can't conjure the brain cells necessary to show basic hand eye coordination, much less teamwork.
If you can't tell, I get mad playing this game solo, because the derp levels rise to astronomical levels. Whenever I'm forced into the tank or support roles I just want to pull my hair out in frustration as nobody seems to know how to either back up a tank, or properly push with whatever support I've picked. No Soldier:76, it's cool that you want to run out through my shield to miss all your shots, it's not like I was blocking that turret from hitting you so you could throw it away further forward than the last time. And no Pharah, I'm not going to hit my ult as Zenyatta to save your sorry ass from a rip tire. You had 5 seconds to hit that thing when it was driving straight at you, and you just ran like a bitch. By the way team, when I hit my ult, it means push forward and start shooting everything, not retreat like a bunch of little shits to lick your wounds. I'm literally making you invulnerable for like 2 seconds, and then healing you at a rate that might as well be invulnerability for another 2 seconds. The least you can do is at least TRY to kill the enemy.
This is why I like playing the other class archetypes. At least I can make up for the rest of my team's incompetence by actually killing things at a wholesale level. It's a sad day when you have the most damage on your team as Zenyatta.
