I just recently came back to the game a few months ago and I'm still getting caught up on the 20+ game. My first toon that I played in the end-game I didn't have to really worry about the crazy quest repetition rules as I was just getting my 20 tokens and TR'ing. My next toon though, despite having a gimpy build for current EE's will do just fine in EH/EN content and I plan on keeping him there for gear/plat farming and Epic Destiny grinding to get to the ED's I want for future lives.
What I need to know is what quests are the really good ones for ED farming at 25 so I can avoid farming those on the way to 25. I don't want to put myself in a situation where only a TR will allow me to farm ED's effectively as I'm currently busy with TR'ing another toon several times right now. I want to be able to park this guy in the 20-25 range and largely ignore him, getting ED's/gear/plat as I need a break from the TR grind for several lives on the other toon.
