Last Thursday, I was in a Manticore (with a Corruptor) that was moments from server maintenance, so I turned on my stealth and ran to Hopkins. I jumped behind a crate where a Paragon Protector defeated me, however, I had a single self-Rez temp charge, so I punched it and got back into the game. I Teleported in an Invul Sentinel (our Tanker was fighting in spawns), pulled in the Dark Corruptor whole the Sentinel took aggro and once the Dark Debuffs were up, ported in the rest of the team. We finished with roughly 30-seconds to spare (After seeing the durability of that Sentinel, I promptly hopped on my Water/WP Sentinel for most of the day ;D).
Sometimes you get fun teammates, sometimes you get some that aren’t. Your experience sounds like you’ve definitely found a candidate for the Ignore list.
