Removing the tiered requirements for taking higher level, non-travel powers would not make the game more fun or even -- it would just let people drop their training-wheel powers and become more god-like. This type of system would only work if you the power sets weren't tiered but branched -- like Galactic Civilizations. Example: Concealment would have five slots: the first slot would give you Stealth; the second would build on the power and give you Invisibility or Sneak Attack (+DMG_, the third slot would build on Invisibility and give you Grant Invisibility (Individual) or build on Sneak Attack and Ambush (+DMG +Knockdown); then Grant Invisibility (Mass) or Unforseen Attack (+DMG +Knockdown +Fear); and so on. I think that would be a complicated re-write.
I suggest granting an initial travel power at level one or character creation. While familiarizing yourself with the city maps is great and highly encouraged, moving around the maps while running from mission to mission is time consuming and most players know if they want to be a jumper, speedster, flier, or TP'er at the time or character creation. The initial sprint, slide, ninja, and beast are helpful but do not compare.
To build on that point: travel speeds should be the same speeds across the board: MPH/MPH for jump, super speed, flight, and teleport should be the same unslotted for each character.
Field Medic as a toggle. Aid Other and Heal Self should be the same speed and healing capability as a Dramatic Improvement (level 2 green). Healing animations could be sped up and simplified by making it similar to granting super speed buffs (just making it green by default).
Get rid of Group Fly and create a very cheap, very basic jet pack that you can get from any vendor while leaving the more expensive prestige jet packs at the same price 10k/hr..
Invisibility should have a better defence bonus even if you are detected (ex: Rikti).
Invisibility should be available before Grant Invisibility. Why would you be able to make someone else invisible before yourself?
It'd be great if different Origins either had different bonuses, penalties, and animations for each power set. I know this would be a big rewrite and complicate coding but...
