Assists could benefit from a rework
How many times have you tanked or baited, and didn't get an assist for the enemies' deaths. How frustrating was that? How awesome would it be if you could get assists for tanking damage for your allies in a fight?
You already get assist for shielding and healing allies, why not also get them for tanking for them, or for baiting enemies for them? That takes skill, and daring, and sometimes immense risks! I think it deserves a reward, how about you?
