Strongest non-ultimate ability?

[quote=lolanea]I'm curious what RoG thinks the strongest single non-ultimate ability is considering both damage and utility? Some potential candidates I've been considering are Blitzcrank's Rocket Grab (awesome utility), Sion's Cryptic Gaze (1.5 second point and click stun with an amazing ratio), Nidalee's Javalin Toss (huge damage and range), and Anivia's Crystalize (One of the highest skill cap moves in the game, and game changing when mastered) What do you guys think?[/quote]

[quote=IShouldGetALife]I'm not sure about this being the best ability but full length lissandra e is the biggest blink in game and makes you able to go through pretty much any wall. If I was to say the best ability it would probably be either veigar or nasus' q come late game they make a ton of difference in a fight that nuke that an extremely tanky champ can pull out and that extra ap is amazing.[/quote]

[quote=Vynertje]Anivia [[crystallize]] indeed. This is the most game changing skill I have ever seen. Another one would be Kog'Maw [[bio-arcane barrage]] or tristy's attack speed boost, dunno the name.[/quote]

[quote=Meiyjhe]Most OP skill I believe is [[rewind]] :D Allows long CD's to vanish in no-time. Imagine if Karthus, Shen or Soraka would have this ability, non-stop global ults :O If you want something more game-changing, than indeed Crystallize, pull abilities and [[pick a card]] maybe :D (dem 3 spells in 1)[/quote]

[quote=A Chubby Baby]Requiem. Yes, this is a non-ultimate ability :)[/quote]

[quote=Kuukai85][[Ryze]]'s Q. CD and tons of dmg without ap items, just lot of mana.. And it's easy spammable.[/quote]

[quote=OTGBionicArm][[Wither]], IMO.[/quote]

[quote=IShouldGetALife][quote=OTGBionicArm] [[Wither]], IMO. [/quote] I don't reckon it's the strongest anymore since the nerf sure it cripples movement speed massively and still a pretty strong debuff for AS but against people like GP or most mages it won't phase them[/quote]

[quote=OTGBionicArm]Still shuts down AD carries that aren't blue [[Ezreal]]. :p[/quote]
