I need some advice to choose where i roll on guarantee. I lack lancer, rider, assassin SSR and waver. Lancer and rider will give me new SSR servant so i fine whoever i got if i roll there (except medB), While assassin and caster have a chance to give me a dupe. I can pass for jack cause i already have jeanne and shiki welfare is enough for me. But its kinda hard to pass 33% chance to get waver cause its WAVER. Should i go to roll on Lancer/rider for guarantee new SSR or gambling on 33% chance to get waver?
