You spawn, you run to a node, and you fight people there. There isn't a whole lot of depth to this in League of Legends. Don't get me wrong, I love LoL. But you only have 4 moves. Generally speaking there isn't a lot of distance between someone performing with robotic optimal precision, and someone who is pretty good. In fact, most of the opportunities for extremely good play came on Summoner's Rift, where someone highly attuned to their character might sneak in, get a kill, and just barely return to safety. Here, there would be no point in that, because they would still control the node.
So if twitch gaming skill is out, what is left? From what I've seen, it's pretty much just spawn, run at each other, use your skills, some people die, some live, cap nodes, repeat. Is this fun? Sure! Is it..."filling?" Not really...There's hardly any way to distinguish yourself, or to do a good job. In SR, you can leave the lane with 200 CS, or gank extremely well on your jungler and help the lanes, or ward their red and ambush their jungle and cripple him. Dominion? You can run to a node, fight, die, or live and cap. And this is pretty much all you can do.
Meanwhile, the people that do the dying, wind up with more or less the same amount of resources as the people that do the living. This helps prevent a slippery slope, sure, but it also has a really annoying Mario-Kart effect where comebacks can happen out of nowhere. Again, fun, but not definitely not satisfying, as you're either robbed from your win or handed a win you didn't earn.
Another point. Some champions are absolutely off the wall insane in dominion. Rammus is an auto-ban, no questions asked. Jax, Akali, Irelia, pretty much all the tanky DPS reign supreme here. And in the spirit of free gold, and 1v1 and 2v2 skirmishes, melee carries like Tryn and Yi thrive as well. In the "real game," these heroes, and others I haven't mentioned, are held back by various things, either poor laning phases, ability to be counterpicked by someone that can outlane them, or being relegated to the jungle, or having to go up against a full team of 5 at one time who can focus them down. None of these elements exist in Dominion. So yeah it's fun to finally get to play some heroes that can't find a place in SR (no im not saying every hero I named above can't find a place on SR, don't be stupid), the 5-man tanky dps squad is REALLY ANNOYING. And you can't out-lane them, or farm more gold than them by securing dragon, you can't outposition them in a teamfight. You just gotta go head first against them, and pretty much get mauled unless you're playing a similar comp. There's no finesse.
TL;DR: Thier is no skill in Arthai basin, Only in Artic valley.
One final note, I've noticed one thing in Dominion that stands out to me as a unique skill. Knowing when to towerdive hardcore, and when to have one guy channel the tower to disable it and to distract the enemy. Indeed you can even trade off channeling the tower for maximum disable time and distraction. It's pretty fun in a premade on vent. Good luck EVER achieving this in a pug. And besides, it might not matter at all, based on the 2-4 champions involved in that fight--it might be altogether one sided.
