Though riot decided to Nerf some agent , Some agent still need either a buff or a Nerf.
Agents that need nerf According to me :-
1) Killjoy - Too powerful, very annoying to play against and her Ult is just the best ult in the game.
2) Omen :- not very Powerful but still the flash is so insane and 1 way smokes are annoying to play against. Also 2 TP should be reduced to 1
3) Viper :- Viable on almost every map And very strong in both attack and Defence.
4)Kayo :- Not very used agent but Kayo has almost 100% pick rate on Ascent ,
Agents That needs a Buff :-
Harbour :- We saw some gameplay from harbour but It's slowly decreasing. I think cove still needs a Buff, The inside Smoke should remain for atleast 10-12 sec. Also ULT just give some buff to teammates may Be teammates inside Harbours Ult circle get some heal or Stim.
Cypher :- Killjoy is just like a Queen in the current meta , A KJ Nerf can revive cypher , may be Cam Tags Just give a Decay Damage of 20-30 hp per Tag so Players Don't disrespect the tag And Remove it to get rid of decay
Astra :- Give her 5th star back but a timmer on 5th star , Like she Has to wait for 30-50 sec to use that star
Neon :- Very under rated agent , a small tweek can bring her back in meta
Chamber :- Increase TP range and Give 2 trips With Same range Or remove range on trip . Also sherrif 100 creeds per bullet
Deadlock :- I mean She is a Dead agent Barrier type agents are still useless in this game , Sage Get some value on Icebox coz her Wall protects from Bullets .
