I actually find RoD balance very fine but the question is whats the difference between Battle Cry and RoD now? For the ones who still don’t know Battle Cry ring’s “you can’t lifesteal” downside is removed now. So basically RoD uses focus too if you have and Battle Cry only uses health instead of focus. If I don’t use focus (which my current build always darin focus) RoD becomes Battle Cry already. I don’t understand that why did you just merge those 2 rings into 1.
There are some enchants that work off having Low-focus, and some that work off having full focus. The respective rings will allow those play styles each.
So which ring you use will depend on the conditions you want to maintain, or simply how you want it to be utilized. As a back up resource catch, or main. If you use life-steal you may use one, but if you do not use life steal you may prefer the other. Etc.
