I don't know if it breaks TOS to post quotes and so I'll paraphrase the comments appearing on General Chat on the Orien server (from many players).

1. I regret coming back, now that I know about the impending TR changes.
2. I'm done with TR after U20 arrives.
3. I'm done with this game after U20 arrives.
4. This change sucks.
5. I'm new and I wanted to enjoy this game, and this is what they plan to do?

There's not a single comment that I've seen that is in any way complimentary, regarding the upcoming changes to heroic TRs.
