See why i want players to summon during rates up is not wasting gems... It is saving them. With the amount of units in the game getting the one unit you want without rates up is less than a 1% chance. With the current rates up system most the time it starts out as a hugher chance and gets higher and higher every summon for 8 summons then stays at a very high rate. It saves gems getting good units so you don't have to summon until something else comes out that will improve  your squad greatly.
