The q ability should be reworked. First of all it doesn't explode on contact but rather explodes after a certain time which mean there are no lineups potential you have to straight up expose yourself to the enemies and throw it. This might be one of the major reason why she won't be picked over omen because omen paranoia is way too strong for stalling the enemies and site execs.
The E ability should be given larger range, this is another reason why she won't be picked. The whole smoke after dying seems overrated. In a normal match if your controller is Astra, teams play for postplant with suck and stun on tap of spike. And omen stays alive too till the end. The only reason why omen is so aggressive is because of his tp, the tp creates space for your teammates if your duelist has died or goes in with the duelist. This cannot be said for clove, sure you can get healed up but you Wil never create space even if you get the kill.
C ability is fine it's just brimstones stim beacon and Reynas overheal combined. But again it's a selfish ability which doesn't help your teammates if you don't get the kill.
Her ult is fine too ig.
