I do not miss 2CP one bit.
Flashpoint, clash have their issues, and mostly maps themselves and not the format (Throne of Anubis is the worst offender for clash).
I think for many people it’s nostalgia talking, because the same people will also complain about the last point of clash being pretty much impossible to take, yet forget that last point of 2CP was the exact same stall and impossible uphill battle on attack, but longer, and the game wouldn’t end after that since you would rotate in comp.
There were also cases of the opposite where each team would take both points, match after match, with games lasting half an hour or more, it was insufferable.
