at the time of writing this we're in 1.08, so I hope 1.09 will fix at least these:
Sound cutting bug MP and SP
Ascendant refusing to animate
Kandros refusing to speak when teammate joins mid match in MP
Sync kills as much as possible
(they're still there)
Increased amount of bugs and lag when joining mid match in MP (enemies not doing the death animation etc.)
I also hope they add platinum difficulty and new weapons and fix the Reegar stutter
Massive FPS drops when doing 5 or more combos with the same power.
This is just rapid fire answering and obviously not everything.
