To be fair, I don't really care for level of mythic really being a major decider as to how much damage a mythic does. Most casual players aren't going to have low level mythics on their first playthroughs, so to design them around those levels is kinda awk
Apoc used to have one of the most consistent damaging builds when exploding triggered lifesteal back in 2016-2017 era, and pure was meta for a good chunk of time in 1.19 as well- aside from its initial release where spell damage raw was multiplied with spell damage%
I can't say much for the damage output apoc does, as I haven't seen or tried it, but I do feel pretty let down by the fact that they touched up a mythic that nobody cared to have touched up, rather than looking at other mythics like spring, sunstar, thrunda, etc. which all are really cool designs but just fall so short of other options (and pathetically enough, crafted options). If they had looked at all of these alongside apoc, it would've been fine, but it feels like kind of a punch in the face tbh. Especially with spring and how it has underperformed crafted bows for years now with no changes
