We’re mostly going to see how this next patch shakes out, since it has a ton of changes in it already.
That said, we would have liked to keep the Junkrat buff at 140 from a pure DPS stand-point (especially against Tanks/Barriers), but it was just really pushing it once he could one-shot 200 health heroes with a 50%+ boost (Orisa ult, Nano, Baptiste ult, etc). We experimented with making the grenades no longer explode on enemy impact once they hit a surface (as a way to nerf his spam, without affecting direct hits) but it felt really weird and kind of broken in a lot of cases.
So possibly Junkrat buffs and some different Reaper buffs, since the pure passive healing buff was really problematic at the lower ranks.
