Svarog doesn't get replaced for Haruhi tho
...Svarog is more so preferred than Uriel after Haru and Frey come out.
Apollo too.
It all depends on the player, tho... I don't have Svarog on DMM and I have Uriel. I wouldn't replace Uriel for Svarog until I get a higher grid because once you have a decent enough grid Uriel does nothing aside from be fast. Everyone can burst for 2M+ once you have a phantom grid... that works
