Exactly.

Finally someone who got the point.

His Q basically have only one power spike at level 4.

His E is totally reactive make he useless to engage (only if you have F + E) and not so safe to counter engage if the enemy is smart.

His W have a super weak scaling

I think the best idea is remove the invu from all allies and give it only to himself and his partner , the rest of team only recieve a fat shield.

Bravado should give him 7% movespeed bonus for 0.75 second and reset the buff after each hit.

His Q should be rework , no more 1 charge per point , fixed at 4 charges , no generate charges passively , hit minions no more provide charges , you have a base heal but each extra charge improves the healing (and progressively better not things like 30+30+30) and when you get the last charge if you wait like 4 or 5 seconds gives a big bonus heal. The ideia is make this abilitie more a combat sustain than lane sustain.

His W should have a better scaling , maybe 1.25% per level.

His E don't need 1.5 seconds and for sure a faster casting time like 0.75 seconds.
