Still it would be a good thing to "nerf" the WoL. Regarding Azem's crystal, my thought on this is it does contain the technique to invoke people, but the amount of aether needed to be done is up to the users. No aether, no invocation. Concerning Hydaelyn's benediction, now she's vanished, I don't think it should remains as it is, it should vanish along time as well. It doesn't mean it gives the WoL his/her strength, but regarding primals, of any sort they are or wherever they come from, it doesn't lessen the fact that anyone can be tempered, even though we have now a mean of healing that affliction. But even with that, we still have Vrtra's scales protecting us from tempering, so even without Hydaelyn's benediction we'd be doing fine. Devs just have to find a new way to make us feel new threats for the WoL and the main cast, that's just my thoughts.
