I'm going to go through each of the specific major changes that broke Deadlock last patch and explain why this has ruined the game:
Troopers no longer change soul sharing rules after laning phase ends, which is at 8 minutes. (meaning 2 heroes don't split souls past 8 minutes)
This means when...
She has a huge katana yet punches with her fist. Make her the prime melee hero of the game, not only Abrams.
Give 3 a passive that either is always on, or that actives only on targets slashed by the 3.
Melee hits will use sword, have increased range and scale with spirit. Actually cool.
