I've come across multiple threads (e.g. here, here, here, here, or here) that use the term "OP-ness". What does this mean?
All I can glean is that it seems to carry a derogatory connotation, especially towards something new. For example:
(1) For one, many people do not like the OP-ness of the new Kerbodyne parts, which is funny, because the tank you are quoting is actually worse than the Jumbo.
(2) I feel like survivability (on the part of Kerbals) would be an interesting nerf to the OP-ness of the airbrakes. Yeah great you killed 2000 m/s of velocity in 5 seconds but Jeb is now dead because 40 g's turned him into jelly.
(3) Oh I've had USI for a while, don't worry I just never thought about it balancing out a science lab's overall OP-ness.
Thanks in advance for clarifying this.
