Okay, slow down there Red Rider! Several things going on...
First, what level are you,
currently?
If you push to 30, then you can do an ER, which takes you back to 20 (and you can then do your HTR/RR, as before). The ER gets you an Epic Destiny PL bonus, which is nice.
So... which to do?
If you are in
early Epics, and already finding the quests tough, then it may not be worth it to push all the way to 30. It only gets tougher, and can be a long slog if you do not have the gear, build, AND game experience. And any "learning" gets confusing, since every area is new, every quest is unfamiliar, and every additional Epic ability makes everything that much more complex. (AND you won't see it again for a looong time, so are less likely to remember it!
)
You could do some farming (of gear, of favor) right now, and then TR, and ignore 30, and start a new (and better!) life. That totally works.
Sometimes it's better to cover "the basics" (1-20) again, THEN go to 30. But ymmv, just sayin'.
