Vi abilities changes to make her more viable in this meta

Since vi is more like a all-in tanky-ad damage gurl, she lacks defensive plays (she only can q back as a defensive play and it takes a good 7-15 seconds to ahve it back so its pretty useless in teamfights). Compared to other jungler that rules the jungle now (khazix slow and jump and invisibility, rengar slow and root, jarvan kab and low cd dash away and even his ult used as a defensive way), I feel like she needs her gameplay to be changed a little bit. She doesnt need buf or nerf, she needs small changes and here is what I suggest :

Passive : switches with w (denting blows) but it gets a little nerf (%life removed) Q : same w: Blast shield becomes an active (shield remains for 2 seconds since shes already tanky enough and protect for 1-2-3-4-5% or vi maximum life) and on cast enemies champions within 100 range are knockback (not kab because we dont want yasuo to ult on that) e: unchanged r : unchanged

what do you guys think?
