You do realize, the fanbase who enjoys those is relatively small?
The main Halo Fanbase that has been around for years, HATES everything you listed. Just because I at times use Evade does not mean I LIKE it, I am using it to counter what my enemies are doing. But do not confuse the new crap in Reach to what Halo Gameplay IS. Halo to me even with armor abilities is about Shooting, Grenades, Melee. But to some folks and I think its safe to say even you, like Evade because it takes away Shooting and grenades out of the picture. Sword, Shotgun, or Hammer with Evade is the worst thing in Reach, I can use the same strategy to get kills but as I said above, Halo to me Shooting, Grenades and then Melee. It is an FPS not a First Person Melee, if you want a FPM then play Breakdown on Xbox.
