A shield and a stun are useless for a melee carry?

Sion.

definitly sion, he is ugly, doesent have any " beuty" in his skills, his stun get out of his stomach and looks like a ***** , his shield looks like sweat hahaha and the explosion its so disappointing, its like 10 long seconds and pfffff he just shook his sweat and his e i think, just turn red his axe hahahaha. and his ulti is like "ummm what we should so with this, dunno just put lifesteal and stuff",
even his skins are ugly

Yorick. 3 button smash. Repeat. Ult adc. Repeat

A shield that's complete garbage unless you're AP and a stun that lol

"melee carry"

Melee carries suck and you know it. Especially one that has no abilities that scale off of AD.

Darius.

Sorry, had to say it.

His shield shields for nothing if he builds AD.

His stun is a terrible gap closer. Even if he manages to run the distance before the stun is over, he has nothing to stick onto his target (Unless he gets tons of MS items). Compare this to Irelia, who can gapclose and slow/stun, Xin, who can gapclose and knockup, Renekton, who can double gapclose and stun, Yi, who can gapclose and then stick to his target using massive movespeed, Tryn, who can gapclose and slow, Riven, Garen, etc. etc. etc.

Sion's stun is easily THE WORST gapcloser out of any AD melee in the game. AD Sion doesn't have the burst to do anything during the stun. So yeah, it's useless.

Current Trynda is impossible to balance properly because he'll either be ridiculously powerful or nothing but pubstomper due to the way his kit works.

You have obviously never just stopped with wiling and made the enemy think you used the ghost spell, they keep running forward, you run away, "OH **** IT WAS A FAKIE". One of the most rewarding things ever

I always thought karthus has a lame design. Turn on your toggle, run into team fights. Either get focused and still do absurd damage, or get ignored and do even more damage. He's so one dimensional, and is not fun to play as, with, or against.
