In WotLK, he was present at a small camp named Dragon's Fall in Dragonblight, where he failed to kill a frostwyrm with his dragon hunters' help. The player and their allies kill it for him. A minor quest over and done with quickly.
In WoD, he sends the player in Blasted Lands to rescue some Horde prisoners from Iron Horde executioners. He also sent a goblin to scout the Dark Portal, and you go finish the job. Then he says the Iron Horde is bad and have to be stopped. Later, he gives you your scout quests in your Garrison.
In Legion, he represents the Darkspear tribe at the PvP Prestige Rank 2 quest in Undercity.
Hardly enough development to be a leader. And troll tribes are like monarchies, the son takes over when the father dies, and Vol'jin has a son called Yenniku (deceased in Cata), who is described as his "youngest" son, meaning he has older sons offscreen, along with his offscreen wife mentioned in Shadows of the Horde. Yenniku is fully grown at the time we see him, so that means his other sons are perfectly mature enough to take over leadership of the tribe.
He's not nearly on the level of the other WC3 heroes. Not even his fellow playable characters of the WC3 campaign he's found in. He had a bigger role than Chen Stormstout did in it, who was basically just "hey, try this brew, oh you don't like it? Huh, needs something else I guess, I'll run around with you now". But since WC3, Rexxar continued wandering around in Kalimdor, still doing his thing he always did. Rokhan was never seen until WotLK, when he had the most minor of roles. Then Rexxar had his thing in Burning Crusade, helping out with his old village in Outland. Then in the pre-Cataclysm event, he was in Orgrimmar, defending the city from rogue elements. A minor role, but cool. Then he's doing stuff with the Hunter order hall in Legion.
And Chen had a lot of development in MoP, arguably more than either of his fellows, and is now at the Monk order hall in Legion.
Rokhan only sits as the Darkspear representative in the PvP prestige rank 2 quest because he's literally the only notable Darkspear character Blizzard already had lying around that had the largest amount of people who would recognize his name. Not because of any so-called development. If Vol'jin's sons aren't in charge, then technically it should be the chief witch doctor of the tribe, Master Gadrin, the lowly level 12 questgiver in Sen'jin Village.

Alliance constantly puts tradition and wishful thinking before reality (see the high elves being sticks in the mud while the Blood Elves killed animals for nourishment like everyone else in the world every day for breakfast, lunch, and dinner). By all accounts, Muradin should be the leader of the Alliance after Varian, as he has the most clout with Khaz Modan, Stormwind, the gnomes, and I'm sure the night elves and draenei don't mind him. Genn probably has less popularity among the people, but everyone loves Muradin. He has experience leading in both domestic and military matters, having been king of the Frost Dwarves in Storm Peaks for years, and being a prince of Ironforge for so long, and now being leader of the Bronzebeards.
Velen shouldn't be the leader, he's best suited as an advisor.
Tyrande is a hack and can't do anything right, so she's out too.
Malfurion doesn't lift a finger to do anything unless it directly affects Tyrande. He couldn't care less about his people. See his pardoning Illidan for killing 4 villages of Night Elves because he saved Tyrande, and then see his sitting back and doing nothing while the Horde rampaged through Ashenvale in Cataclysm, then having the gall to lecture Leyara about not giving in to hatred when her child daughter was murdered by the Horde because of his apathetic attitude toward their advancement into Night Elf territory. Malfurion is all for giving into hatred when its HIS feelings that are hurt, immediately sentencing Illidan to death when he thought Tyrande was dead in WC3, then immediately forgiving Illidan's slaughter of 4 villages and tons of Watchers when it turned out that wasn't true and Illidan helped save her.
Genn has military experience, but I don't feel he has the popularity or charisma with the rest of the Alliance for them to follow him.
Anduin is a child. In peacetime, an inexperienced ruler with good advisors is fine, or at least having him attend strictly to domestic matters would be okay. But in times of war, they need someone strong at the helm, and strong and experienced Anduin is not.
Muradin is the only one with the popularity and experience in all aspects of leadership to fill the role.
