What in your mind makes a Juggernaut?
The power fantasy (A term I've seen thrown around upon occasion by Rioters and others on these boards) I've always understood them to be is playing as this big, buff warrior, or some colossal being that comes barreling down at you with steps that make the ground quake. Oftentimes with this hypothetical colossus wielding some huge weapon (Doesn't really matter what, as long as it's Big and powerful looking) that they use to just completely CRUSH those that dare get in their way.
What makes a Juggernaut (Or any other champion that can fill that above-listed "Power Fantasy")?
: Q (Ever since the Jugg update) is delayed, allowing attentive players to adapt. E is also slightly telegraphed, as the pull is not instantaneous. His R is most effective when he has Noxian Might.
: His Mist-Walkers only focus a target if they are marked by his E, and the same applies to the Maiden.
: He must build up his Q stacks, and they are visible to friends and foes by clicking on him, which can help a player gauge his threat-level in relation to them.
: Her potential for trades is situational, as she must be around her passive tentacles to really be able to do her damage.
: His Q is a 1,2,3 in rapid succession, so if a player can put some distance between him and them, it loses it's effectiveness. (You probably could come up with something better for him than me, but I tried)
: Ever since the Jugg update, he usually wants to focus whoever his current Villain is, and he also wants to have a singular target to maximize the effectiveness of his E.
: He wants to fight in his E zone, as it provides him passive bonuses, as well as get his Q AD Buff.
: He wants to keep you close so his W burn can wear you down, commonly accomplishing this by well-aimed Q cleavers.
: He usually opens with his Bear Stance, then switches to whichever next one best fits the current situation.
: He wants to mark you with his Q so that his W will prioritize you. If that isn't enough, his E can do it if he lands it, and the dash is very telegraphed.
: He tries to keep you in the fight with his toss, so he can hopefully wear you down for his W execute.
: She can only ult when at full Rage, so the player knows when her windows of power are.
or
rage effect, or
gradual MS boost). When Warwick has access to his W's boost, it makes him move MUCH faster than a Juggernaut. Juggernauts are always slow, and often depend on their CC to keep targets within their grasp.

, or fellow Juggernaut
and so on). Divers, while not as squishy as say Mages, or Marksmen, don't have that same level of innate tankiness. They also have to go for a more "Middle-of-the-road" build, or equal defense and offense (Unless they're doing extraordinarily well), while Juggernauts usually only need one offensive item, and can go full tank afterwards most of the time.
for some reason with all of his fancy slashes (Q, R and so on).
is a juggernaut
if his shout lands he can follow up with decimating blow to hold you down longer.
is... just a mess at this point with a not so clear direction of what he is ( I mean is he still a tank, a juggernaut now, what is he?)
absolutely destroys him, and he doesn't do craptons of damage on his own unless you let him dance around you.
is War, so that's taken. Or, we'd just have to get something completely NEW that hasn't appeared or been established in Targon yet. I dunno, just spitballing here.
