your focusing on the top of the tree where they can if they want add  20 to their TOP SQUAD .. ( 18 for me ).the fact that your not that level...or poss lower you have more of a chance of saving up the un as you level to buy them AGAIN for free .....patience and perseverance and you will have them 
the game from start to finish will offer you all you contribute to your game and the way you play it ..there is plenty in my sqd  who dont pay to play and are solid  characters with GOOD SKILL allocation ....and they have plenty to keep them occupied .
