The problem with Wars is they have no costs for us. We play Wars for free -- in game words, no crystals required except to rush the troops/air cooking time -- so isn't interesting for Disney to increase the rewards. I think they only gave the old Elite in the crates after the "Summer of SW" because wars were losing players, and many big squads have members that use crystals to fill starship command or rush their loadout to attack again while they have Takodana.
My Imperial base has all old Elites maxed out to 10, except MTV -- what means I will get only frags for MTV until have it maxed out too. My Squad is level 45 so I'll keep playing to help the Squad. While Rebel, only Kessen is maxed out, then the frags keep me interested in playing wars while my Squad already reached Level 50.
I would like to see frags for other units in the War crates, as Lord Vader/R2 & 3P0, TXs, Tie Striker/Fang Fighter, Security Droid/Drabatan, Death Trooper/eAT-TE, or even the hero spider, but they are Units attached to Special Events that Disney uses to take money from players buying crates for them in the store. Giving these units for free in war rewards would be a shot in the foot (or paw, for Mickey of course)...
