I disagree that minefield should go away when he dies, however I do think it should go away when he revives or MAYBE some set time after he dies like a couple seconds. It feels to me like it would be strange experientially if his ult just popped out of existence the moment he died, especially considering the style of ult that it is, like if bob just disappeared when ashe dies. It’s not a perfect analogy but they’re reasonably disconnected from their users.
so let me get this straight. you want the second worst tank ultimate to disappear when ball dies because you don't know how to look both ways before you go into a field. stop trying to nerf the worst tank in the game, L skill issue
I dont see why you're making a big deal of the Sigma's buff. As more heroes are being released it gets easier to counter, not sure why it would have to be reverted
