Everything should be left as is. Everything is about trade offs. You can't make use of these things unless you specifically invest in them to make it work. I get to spam atros in my core, but my other healer doubles my hps. That's the trade off and I don't see why it's an issue.I dont Like the Changes but all the %based ult cost reduction should stay(zos surely will Go for those as well).
Let us have ultspam If WE heavily Invest into IT.
