Retro missions: Professional loop

[MNaeemi777]

Retro missions are hard enough in higher difficulties and adding professional loop makes it so harder.

Earlier I suggested something about retro missions, but when new waves got added for retro missions only:

Early Access version 80.2

IA, all retro missions have beginner, intermediate and advanced loops, like some waves of Chicken Invasion, which are same, but appears on different difficulty. (Spin Class & Spin Cycle) These loops should be depended on the difficulties of retro missions and in the case, we need some new waves for retro missions with same loops. Please think about it, when you had time. Thank you. EDIT: Retro missions may have randomized waves like other mission types and not exactly specified …

Loops’ difficulties should be based on difficulties of daily missions. (e.g. 0%-35% for beginner loops)
Because flying retro missions are too boring. Always 4 waves and they loop again and again, until the boss wave. Droid foods is now more interesting and not so boring as CI4, so why not making secret content of the game more interesting for people?

EDIT: Maybe 0%-50% for beginner loop, because some players use higher skills.
