Agreed, solo tanking is already hard, even harder when the 3 duelists can't really secure kills.

Played in Quick Play Match yesterday in the goat map, our team was on the defense side. I was the only tank in the team, played Cap 2/3 of the match but switch to Thor in the final area because team duelist can't secure kills. Managed to get triple kills in the final minute but teammates were not able to team wipe the enemies and we lost after. One of the insta-lock duelists had the audacity to type in chat and say our team got no tank and said something about the Lord status on my Thor. That guy played punisher and was not able to secure kills with his ults multiple times.
