I think your outlook on Squad Arena and CG's is quite different. You are aware the rewards are pointless and wish to use it as a Sandbox mode. CG, see it as a competitive environment where you strive to get the best reward possible.
It's not really 'that' suitable as either. It isn't/can't be used very well as a Sandbox mode (although) it's the best we have. The rewards are so poor, I doubt many care about it. For me, it's 600k credits every couple of days.

All that said, I think this would most certainly be a big improvement. I'd definitely get behind this idea.
