Angry Ego (Time Traveler)

If Angry Ego only deals 10% damage, it should also only give you 10% thorn retaliation

That's not the issue with time traveler. It's really easy to get thorn block, and all the secondary effects still are full. Plus, if you go for a vulnerability build, each hit will be doing up to 60% of your normal attacks anyways.
The issue with time traveler is that it takes too long to initially launch an ultimate in the first few waves, so you don't have any flexibility to go for investment perks like aging once you are higher ascension level.
