Please help my squad development, I went down the random line! Need to salvage my squad advice.

@MasterSeedy @Gman8675309 Do you mind if I add in a quick question to this thread?

Why, in the post about the stores, do you say to get Malevolence all the way to 7* before starting Negotiator, instead of unlocking both of them 5* first? I personally see the pros and cons of having both at 5* as well as the pros and cons of having one at 7*. I can't decide what I want to do, as I'm unlocking Malev soon.

Thanks!
