I think its probably due to my lack of maintainence of the rubbers themselves. All the rubber that ripped are from mags that came from a friend of mine and I dunno whether he maintains the rubber seals or not by oiling them once in a while. They looked fine to me before the game (no cracking or anything). The rubbers all ripped from the side thats closest to the bullet valve. The damage looks as if something pulled or pushed the back side of the rubber too much causing it to rip parallel to the direction of the hammer strike.
Another issue could be a loose BBU. If the BBU is too loose, the nozzle will have a tendency to point downards since the BBU is only being held from the back via the firing pin screw and due to gravity. the loading arm on the BBU may have been pressed against the rubber and causing it to shear.

Are you applying oil to your gas?

However; a high flow valve is probably needed for the valve to close quick enough since I tried it on my stock MEU mag with the SD nozzle + NB valve spring and if I remember correctly I ran out of green gas in 5 to 6 shots.

Can you explain your theory on how a stiffer floating valve spring will create a better seal? Because by theory, it would actually make it HARDER to get a good seal, as its natural state is to resist closure of the valve.
What you're experiencing with poor gas consumption is the result of the valve not closing fast/hard enough. I've seen this on a lot of setups, so I would never outright recommend a stiffer floating valve spring. It's trial and error on whether it will work in your setup or not. I've never figured out what can make it work and what won't. High flow valves could be a potential solution, although I found that not to be the case with my own 1911. High flow valves, but it still would not work well when I had the 9ball floating valve spring installed.

If I can shoot 10-15 bbs quickly (as fast as I can pull the trigger) and the slide still locks back, I'll go with the upgrades. So far my stock MEU mag in my MEU can shoot 18 bbs quickly and lock back on the last shot with green gas.

If your 1911 is built well, you can get close to a full mag of gas out of it.
I can get a full mag out of one of my setups.
