I was a little mad about Valkyr's nerf at first, but after playing with it for a bit, it's really not too bad.
The extra damage taken when her ulti ends is something that should have been in there from the start imo, and it's probably possible to negate most of the extra energy cost with mods lol.
Overall I kinda like the feel of her ulti now. Feels a bit more costly to use, but still very powerful. It still feels like easy mode, but it seems much easier to end up in a bad situation (and more quickly) if you aren't paying attention, which is really all that needed to change with the ulti I think.
Trinity's nerf is just crazy though lol. I haven't gotten to try it out yet, but sounds pretty harsh.
