The WWE roster for Raw and Smackdown wrestlers, despite how it may not seem like it at times, is in fact a hierarchy of importance. Some WWE superstars are more important than others and higher up on the ladder. The following is my best guess as to how WWE management views each particular talent's level of value, NOT how I would rank them myself.

Triple H, Undertaker, Rock, Brock Lesnar, Sting
Randy Orton, Dean Ambrose, Seth Rollins
Big Show, Bray Wyatt, Kane, Ryback, Mark Henry
Cesaro, The Miz, Dolph Ziggler, Sheamus, Rusev, Luke Harper

FOR SPECIALTY: These are the guys that take precedence over everyone else, for the most part. They're perpetually at the main event level even if they don't show up that often.
FOR MAIN EVENT: High-Tier are always in the main event and never lower than the top of the card, relatively speaking, and seem to only get pushed aside if it comes to them against a specialty act. Mid-Tier go back and forth. Low-Tier are world champs that don't frequently main event but can fill in a main event spot at any time, or a new world champ that is fresh to the scene and thus, hasn't built up enough history to be moved up.
FOR UPPER MIDCARD: These guys are in limbo between the main event and midcard scene. They may have won world titles but don't stay at the top that often or they are close to getting to that level, but haven't quite reached it yet.
FOR MIDCARD: High-Tier are those that are in contention for the Intercontinental and United States championships at any time; Mid-Tier are not quite that level yet but still may challenge; Low-Tier midcarders are used primarily as filler and rarely win any match unless it's on Superstars.
FOR JOBBER: Generally speaking, these guys can't even make it on Superstars and if you do see them, you know for a fact they're going to lose and stand no chance.
FOR STATUS UNKNOWN: These people are either off TV due to injury, suspension, or something else (wherein they have no ranking) or they are currently not in a position that seems like a solid state, such as a newcomer or someone that is on TV in a non-wrestling capacity.
