The latest edition of "Ask Cryptic" has popped up on the official Champions Online site. Check out a snip below:

You discussed briefly on Ten Ton Hammer about balancing ranged vs. melee powers in PvP. However, how is the use of travel powers being factored into this? Whatever bonuses are given to the melee player, he/she still has to chase down the ranged player before attacking, which would be extremely difficult if the ranged player was faster, and impossible if he/she used flight or superjump against a melee player whose travel power is strictly horizontal. What, if anything, is being done to preclude this situation? - The_Dark_Lord

It is absolutely possible for a player to generate an extremely powerful melee combatant, and for that player to eschew any ranged power or disabling power and just focus on damage, damage, and more damage with a smattering of resilience. The whole point to a classless system is to let you, the players, make choices, and for all of those choices to be viable and work in general, but to always have consequences.

That being said, we're going to crazy lengths to make sure that players have every tool we can think of available to them to balance the scales. Lots of power sets have travel power disables, or lunges, or roots, or stuns, or some other mechanism that aids melee characters in dealing with speedy or ranged opponents. Additionally, there's thrown objects. Hitting a flying guy with a flung park bench or a truck or something tends to disrupt any and all travel powers for a few seconds. Finally, there's teamwork. If you really want to be melee master we suggest you get some friends who can balance your weaknesses vs. their strengths.
