with the whole thing about whenever you die in Homestuck there's a chance that you might actually die but your dreamself continues to live as it's own person who thinks they were the original you, are there any god tiers who might be an exception to this? i see it mainly be Heart players and Mind

Nope. Even Heart Players suffer this. It’s like SOMA. When you Die and Ascend, it’s a Toin Coss. An iteration of yourself will be ‘left behind’ and die for good, while the other continues as a stream of consciousness as the Ascended God Tier. Which one you wake up as may be a 50/50 chance.
