I've had that inner debate recently, because I think they said in the last LL that they considered delaying Savage for a week? I don't know if they "could" do it after 2-3 days because they tend to patch stuff on Tuesdays. If they can, then yes 3 days would be perfect I think, because a week is a bit long, especially for patches X.2 and X.4.

I can see the advantages for this, it would give us a bit more time to "prepare" in a way. I'm talking about crafting obviously, and potentially getting the Ext Trial weapon too. While I'm not a pro-raider / World Race competitor, I like to get in savage when it's out. But I also like to enjoy what's coming with the same patch (like MSQ and normal raid story). So having savage would not have players like me feeling "forced" into rushing crafted gear, normal mode raids to get into Savage before it starts to get a bit spoiled here and there.
