Petition to base Sylas's gameplay on his backstory.
Melee anti-mage using a knife and punches/kicks Passive, gains brief mana regen and reduced ability cooldowns when he takes damage from enemy abilities Q, short-distance flip with damage mitigation and empowered auto afterwards (Mageseekers gotta be skilled to fight mages) W, passively tracks closest three enemy champion that uses abilities; actively marks one enemy champion to give increased movement speed towards them (He can sense and see magic, remember?) E, lung at enemy champion, damaging and micro-silencing (Mageseekers use petricite and petricite absorbs magic) R, mark enemy; damage from their ultimate becomes a slowly decaying shield (after taking reduced damage), then cast to use their ultimate OR cast without interactions to send out petricite chain attached to his knife and do basically what he does now (Remember how he got hit by little girl's Ult before using her ability? He felt it's power before absorbing and using it as his own)
I would enjoy this character much more than I do what we have at the moment. =/
