I will say that I think if rune of power moved with you, you’d still have to plan and time it if the point is that you enjoy planned, timed buffs.
I just don’t enjoy that in my rotation flow because I don’t think it’s fun or interesting. But I’d at least be able to move more while casting if I took ice floes.
I would hate it less if it moved with me, but I still wouldn’t like it.
