Grit is such a good addition for Yamato and against her too. If she grapples in, whether you're playing or against her just pop the shield. Been seeing double shield items in pro, might start trying that in my own games.
I have been thinking about grapple max before ult for a while now, haven't really done it a lot though. I always feel like max ult happens too late into the game to make a difference, I like the thinking behind max grapple and being sticky, especially against good players on Wraith or Mina, being able to stick to them through their mobility/dispel is so powerful.
Curious of your thoughts on Cultist atm, I feel like it is close to being viable just too crowded out by how powerful the 1600 gun items are, but if the meta slows down a bit and Stalker is nerfed it could come back?
