Hey I'm sorta confused about flying in 4e. Take the avenger Paragon Path Favored Soul for instance. The utility allows u to gain fly 4 (hover). Does this mean that you could move your speed (4) upwards and then hover at that height for the rest of the encounter and be immune to melee attacks? I know avengers don't have many ranged attacks, but even using unarmed ranged attacks will eventually kill something if it can't get at you. This seems too easy and cheap to accomplish than should be allowed, but I don't see how you'd get around it. Thanks!
