I think I have Strike Teams Figured out

Nice to see it broken down in a chart.  People keep saying you can have up to 5 traits but I still can't get that to happen.

I have 5 teams now and 4 of them are level 20 - they've all gathered one single negative - and 4 positives. 

I have tried my darndest to take on EVERY mission the game makes available, on a daily basis - so either RNG is screwing me hard, or there is some sort of other mechanic in play that is stopping me from getting a 5th trait.  

The thing is - looking at the APEX app select your team and then look at the traits menu (especially if you already have 4)  you can clearly see there is only room for 4 traits on the screen, and I have maintained for a while now that I believe this is the maximum in either side.  I have only heard anecdotal evidence saying 5, and now your pictures - so it leaves me wondering.

Still thank you for this wealth of information, I'm sure it will help somebody else.

Also for what it's worth, I put the exceptional human intelligence on everybody, the reason is because if you build for a role - you do get more effectiveness in that role, but you gimp the team for any other task.  With Human Intelligence you can get 94% on Golds as long as you have the right faction buff - and since you accruse other minor bonuses, you can pretty easily achieve a 94% success rate on all mission, while saving some funds from the +40 gear (since funds buy gear in MP, this can be useful).
