It's not revitalizing the champion, albeit that's awesome. It's not the metal ult, which is incredible. It's not even the lore, artwork or anything.
It's the fact that Urgot's old ultimate is now free to be put on a champion who can make actual use of it. An ult that awesome should be able to be placed elsewhere, not hogtied to Urgot.
WiccanBKaplan1 votesThey did keep an aspect of the old ult on his E. The idea of switch places with someone.
ModCaptainMårvelous1 votesThere is so little tying it to his old ult that you might as well say Lee Sin has an aspect of Ezreal because they share Q's.
SkyblazeHydraX31 votesRiot said even months or years ago that's what they wanted to do. They like Urgot's old ult- just not on Urgot. I'm sure we'll see it again in the future, on a more thematically appropriate champion.
Big Lincoln1 votesI hope it's not on a fucking support, that'd be such a massive waste of its potential
ModCaptainMårvelous1 votesOn a support would be insanely powerful. Suppress-trading a carry into your team at the cost of a support is a win-win in almost every circumstance. Hence why Urgot was almost always the anti-carry champion.
Big Lincoln1 votesthey should put it on a melee carry desu senpie
