Idea: Hide a wingman

In this idea you will hide a wingman for a limited time but you have to pay it to hide a wingman. If you want unlimted, you have to pay a lot.
Wingman:
Rare: Duke Spacewalker
Epic: Chuck
Legendary: Hen Solo
Note:
Your wingman has heath. If he dies, he will respawn again and follow you.
In game, your wingman’s attack is powerful (depend on Rare-Epic-Legendary)
You wingman always follow you until you ran out of limited time. If you hire unlimted time, you wingman always follow you forever.
