Gone are the days when melee did more DPS on tank and spank fights and therefore gained an advantage when they didn't have to move. Likewise, spell pushbacks used to play a major role in this type of thing, but with the current pushback mechanics this is a much weaker effect than it used to be.
You and Tengenstein cite V&T as favoring melee, but does it really? Even with the majority of P2 being stand still and pewpew, ranged are still in no great disadvantage from having to stand outside and move from void zones. They can be targeted by the temporary double damage buff, which easily offsets any minor DPS loss they take from having to move every 10 seconds or so--additionally, the majority of ranged classes don't even care about having to move for a couple seconds like that and can simply use instants.
Being melee in the fight is probably easier, but that doesn't mean it yields better results.
In normal, ranged can DPS through P1 and during both phase transitions, while melee can easily have little DPS time during them.
The whole concept of the advantage of melee being that they can DPS while moving (as long as they are close) is somewhat subverted by the fact that most ranged classes can do decent damage while they are moving as well. What does a Fire Mage lose while moving when moving Scorch is about 90% of the DPS as Fireball and everything else is instant?
