Please calm the fuck down and relax. Try one of the techniques the instructor taught you in the beginning of class instead of trying the camel clutch. These weekly bloody lips and nutshots are eventually going to get you in trouble with someone.
I love the fact that the number of students are growing at the school, they just don't realize that the higher ranking student they are rolling with who they think they have in a dominant position and uses all their might to tap, is just practicing a part of his game and could choke the shit out of you time and time again and drive his knee into your belly hard enough to rupture your appendix if you don't calm the fuck down!
"Do you guys think total newbs should be allowed to roll/spar?"
I think so, under supervision of the instructor or rolling with a higher rank.
I just turned 30 and have three kids and have started avoiding the bigger no gi tournaments specifically because of this reason. Submission Wrestling is becoming more and more distant from BJJ in my opinion. Very little technique, lots of take 'em down, hold, win. I'm sticking to the BJJ gi comps for now...
My personal favorite newbie move, aside from the grip of death, is "the Zombie" aka the double stiff arm. These newbies subscribe to the theory that if they keep me completely at arm's length, there's nothing I can do to hurt them. Therefore, at all times, when I'm sitting in butterfly guard, mounted, in side control, their elbows are in their fully locked positions, trying to keep me from getting a single milimeter closer to them. These guys will frequently do nasty spazz moves if you break down their stiffarms. I have been the recipient to several stiffarms to the face when I stripped their hands off my knees in butterfly guard. Not cool.
In my school I make the n00bs focus on position so for the first month they usually roll live for position only. After they understand why position is so important they are allowed to use submissions.
