Is my pulling guard reasons good enough ?
A quick background story: I have adequate striking skills and i am looking to cross train n stuff.
I recently started no gi-BJJ at my university for 3 months, the classes are awesome, but they are once a week (1.5 hours of instruction, 12 classes a semester total) and thats the only time i can attend anyway because of severe time constraints (full time studying as a senior in univ, part time job, MT classes 2x a week, little social life, bla bla bla).
So, whenever its time to roll i always pull guard and work from there, my reasons are as following:
1) figured if i fight ammy MMA in the near future or have to use my power on T3H S7R3375, i would keep the fight standing up at all costs, my striking is my strongest point, in the clinch i think i could hold my own with knee/elbow/push-back-to-striking, so if i do end up on the ground i will probably have someone in my guard (best scenario) or have them mounted on me (worst scenario), either way, i am on the bottom, if i am on top i would GnP and stand up as soon as my opponent shows any hints he knows BJJ.
2) this isnt on-going training, its only 18 hours spread over 3 months that teaches basic BJJ, so i am treating it as a crash course, and thus try to learn enough of something to atleast manage to keep myself from getting raped for when i start seriously training in grappling (judo, BJJ).
3) i find it easier to concentrate on getting one aspect of the game in working condition instead of trying to learn everything at once, i'm not planning on winning the mundials any time soon.
4) our class is filled with muscle head UFC watching ex-wrestlers and there is no fucking way i am starting any clinch games if i cant use my MT, today a guy got taken down so hard he nearly broke a rib and had to sit out for the rest of the rolling, he agreed to roll with me later because i pull guard, i also got my deltoid muscle completely torn and couldnt move my arm for 2~3 weeks after being taken down by a wrestler while trying to BJJ from the knees at my MT club.
5) i can control people better from the guard and occasionally manage to get a triangle choke or armbar (like today), since sometimes i roll with muscle heads i prefer to stay somewhere i can control them and not have them try to crank my neck 360 or do kneebars/ankle locks they seen on youtube, again, this is a crash course and not on going training, i wont learn much anyways.
So, is my pulling guard reasons justified ?
Should i even be worried about constantly pulling guard ?
Am i deluded and should concentrate on something else given my case ?
