One of my fave pub things in T2 was this.
I can't remember the name of the fucking map but it had a gen that kept up a couple of shields in a tower that guarded the flag. There was a vehicle station next to each base. There was some giant fucking mountain range in the middle.
Boring as fuck.
Anyway, I would grab an inv. Go up into the middle. Set out an inv. Put out all the fucking turrets ASAP. Re-spawn in heavy. Go back and stand on this fucking cactus that I had used to set Qings waypoints or whatever. I would sit my fat ass up there for the entire match with my inv and turrets protecting me while I mortar spammed the fuck out of their base front door and vehicle pad. Jesus christ the tears. I would rack up like 75 kills and shit like that while people were crying about cheating and leaving. Meanwhile, nooobs would spawn into mortar fire and it was glorious. I loved that shit. I mean, when no one was around, the best thing to do was to make everyone's life hell in a pub.
