Well, LC is a bit op IMO. Her base movement speed is 320. One skill for 300 heal, debuff removal and + 120 attack speed. That's 3 different skills combined in one lol. 2nd skill is a nice nuke, easily over 300 damage if used well on lvl 4, so the damage is on par with an average nuke; thick is that it also buffs LC making this skill really overpowered. Only her passive and ulti feel reasonably balanced.
Not to mention her nice stat gain, high damage and high hp
She is meant to a ganger hero like bounty hunter, but turned out to be an amazing jungler, laner AND ganger. Overall LC feels like a massive brainfart. In the old days Silencer used to be OP like her with an aura that silenced enemies for 4 sec when they casted a spell, making all channeling spells completely useless
This new LC is on par with that
