amazing what 2-12s can pull off- but I've found their limit for sure. If you play large shows, have a loud stage sound, and prefer your amps tone to the monitors tone you will find their limits as well. Of course these are "strange" gigs 
I'm playing more and more "strange" gigs- ie large outdoor gigs with large stage sound. Played Thursday night outdoors on the beach- about 700 in attendance. Huge sound system with subs- FOH house sounded great. Bass through the monitors sounded meh. Band asked me to turn up multiple times- playing reggae/dub, rockabilly swing, 70s funk etc- with a loud drummer the 2 112s just couldn't keep up (made a solid effort though). Had to rely on the monitors which was fine but not preferable. I depend on the monitors when I'm at the mic doing backing vocals- but when I stagger to the back of stage my cab tone is where it's at....
2 CN212s or even 3 HD112s may be in my future, but then I need to re-think my amp as well to get down to 2 OHMs. It never ends
