Do whatever you want with "epic" TR, it's a new feature that you can make as dumb as you want. We can chose to simply ignore it.
But the changes to Heroic TR are just not acceptable. This is bait and switch, we never would have bothered maxing out Destinies if we'd been informed that they would eventually go away with a TR.
Epic "advantage" is pure dreck, whoever came up this this idea is clueless and should be moved off of DDO. This will simply stop people from TRing.
Make this horrible idea optional.
