Spawning OC's

Just tried to spawn a level 8 OC. It took 12 attempts. Now I have a bunch of level 7 OC's that will go to waste. Possible solutions:

• Put a cap on the number of empty OC's so the other can spawn. Ex you have 5 level 5 OC's the next spawn will be a level 6
• Change the odds when spawning. Ex you spawned 2 level 7's the next attempt has a better than 50/50 chance of being a level 8
• Allow the spawning of a specific OC at a greater price. Ex you need a level 4 you must pay extra to insure a level 4. Double or triple scope
• Allow unwanted OC's to be sold back for half of the original scope.

I'm sure there are any number of ways to make this system not so damn frustrating. Please add your suggestions

I'd be thrilled if I could delete all those duplicates that I don't want or need.

There are many ways to change this. the obvious answer is there is supposed to be a degree of RNG to spawning. Otherwise one of the many options would already be in place. 

Surely this is an exaggerated situation. There is no f**king way you sat there and wasted 44 scope, just to spawn a level 8 oc, knowing you dont have enough people to fill the 7's. If so, my suggestion would be to delegate that job to someone else asap.
