RNG workaround is it possible?

That's completely understandable but it just seems odd that for older events like those that came before relics and other more recent character development updates are made simple by just moderately overpowering toons but when you look at events like general Skywalker it wont matter how over powered and well moded the squads are there is always a high chance of getting mercilessly slaughtered and the only chance of victory is constantly reentering the event in hopes that rng will be in your favor.
