Mash is probably going to be the only shielder servant ever. Personally, I think that’s kinda dumb. I get Mash is supposed to be special and all, but ffs, she’s already one of the best servants, a central plot character, costs 0 points, and is the very first servant you get. Is that not special enough? I think it would be really cool if another shielder servant was added to the game.
There’s also the gameplay aspect to consider. How would you make another shielder servant play? But I’m a moron who knows nothing about game design, so if anyone has any ideas, hearing them would be pretty cool.
