Grasp really needs a buff.
Proposed Change (Melee only) Grasp grants more maximum health but caps off, when capped you are stronger. Health cap = 300 HP, 10 HP per hit. Once it hits cap or you reach a certain level; 4% damage 2% healing -> 5% damage 3% health and mana
(Ranged) Half of the maximum health is capped off, gain mana on procs when capped. Reworked for "surviving" bad match ups. Health cap = 150 HP, 5 HP per hit. 4% damage 2% healing (40% reduced) -> 4% damage 2% health and mana (40% reduced)
Why mana?
Mages tend to go 
into assassins, so they literally have no mana to stay in lane.
Resulting in them recalling more often and having a massive level disadvantage.
Other mobile champs lane longer, can burst you then recall, beat you back to lane with out of combat movement bonuses (runes, items)
Tanks can't rush anything other than 
because of this.
We would see more sunfire capes but it simply gives no mana.
