Part of the time when I was reading Deathly Hallows, and all of the time I was reading MoR I always expected Harry or at least SOMEONE else to act like Kiritsugu from Fate/Zero. Imagine: Enchanted portkeys with no destination yet programmed in attached to home made bombs, flash-bang grenades as a staple in wizarding duels to disrupt aiming/concentration, to say nothing of the videogameesque ability to actually carry around an entire armory with you or heal yourself much quicker EVEN IF YOU DON'T USE MAGIC.

(For those of you who don't know, Kiritsugu is a mage assassin who takes advantage of the Magic Association's technophobia and uses weapons as a regular part of the kit: Mages aren't going to defend against you if you're a mile off with a sniper rifle and they aren't going to defend against landmines if they don't know they exist!)

Edit: Actually, scratch the Kiritsugu idea I just want Neville to cast a shield charm of some sort at his feet so he can rocket jump from staircase to staircase at some point. Pity Quake 2 is five years in the future.
