And that isn't a lame reason? That one of the most powerful beings in the Universe has his weapon blown up by a goblin explosive?

It isn't about what makes sense for Blizzard though. You are proposing alternatives to what already makes sense to Blizzard. If your alternatives are just as bad as what Blizzard comes up with then why change it? If the bow is stupid why not have a stupid send off? If Horde is going to just give it to Alleria anyways why even include Sylvanas as a token part of the equation?
