I would think everyone wants to do as well as possible, regardless of game mode....
I wouldn't think anyone would want to be..... say, a tryfail....but if they did, it still brings us back to being a "tryhard" as you'd need to "tryhard" to fail.
Surely that makes Everyone a "tryhard"? I've now confused myself........
If you ask google to define tryhard it will say this:
-A person usually of little talent who tries hard, especially through imitation, to succeed, usually to gain fame or popularity.
So one example would be that dude with the LMG and target finder who still doesn't go positive, tries to camp around the objective but does not help capture or defend it.
...said the 15-year old "try-hard" that probably hasn't yet lived a day in the adult world of jobs, family and responsibility beyond a 3-page double-spaced book report.
If you're over 15, I feel truly sorry for you that you can't imagine playing a game - read that again, a game - for the fun of it. Enjoy your life, and let others do the same.
