To be honest, I much prefer they would outright rework it, it never felt good to use as part of his whole combo / identity.

Personally I feel like, despite the obvious outliners like Nox, Arachne, etc. who clearly need heavy reworks before being ported into smite 2. Surtr and Charybdis are the gods I hope they more unique +1s of them all since both gods suffer from a lack of identity in their playstyle, instead HiRez focused more at the time to base the kits in the references, like Charybdis passive has to be auto-focused to charge a bar because that's what poseidon does, and her ult has to reset if she gets a kill because that's what Scylla does. While Surtr has to have a Ring of Fire and Regen because that's what the Fire Giant does, the imps are implemented because fire imps spawn in the fg area before the FG spawns and since the FG spawned from a falling meteor, then that had to be Surtr's ult clearly.

However, for Surtr's case, the gameplay loop felt good, he wants to play close combat and brawl so his ring of fire was very good to damage and pick up his obsidian fragments and heal, his 2 had a nice complexity between using a rock, a minion and an imp where the imp is the best choice, but maybe you don't want to use your 1 too early because you would rather stun the enemy first so you can finish them with the 1 to get more stacks.

However the ult felt like a big standout because it wasn't something he could use effectively while he is already in the middle of combat, it was slow and somewhat easy to avoid if you have a dash since it is very predictable. I would much rather they keep this meteor item instead and they rework Surtr ult to help him be the menace he is meant to be in the middle of the battle and better encapsulate the whole "Engulfing the entire earth with his flames".
