Well, I just finished Tangleroot last night on Normal. Having finished most of the level 6 quests on Casual/Normal, I decided I could open up the level 7 quests and the first two I did were the last two quests of this series.
I picked up a nice Resistance +2 cloak as an end reward (that has a +3 cold DR on it as well), so that was pretty good.
I'm going to blow through the entire quest again on Casual now. When I started this quest line, Casual mode wasn't available yet, so I wanted to finish the whole thing through on Normal before starting over again on Casual. I think that's the last quest line left where I had done Normal but not Casual yet.
I won't get anything for it. The XP will be trivial (probably 0 for the first few quests). I won't get any Favor, and the loot will be vender trash. The only real reason to do it is to check off the boxes in the quest table. But that's the sort of anal retentive person I am (it's why I'm a good programmer, hehe).
I figure it won't take long. On casual, it will take me a couple of nights of questing to run the entire line, even given my usual "Explore everything" attitude. Though I may detour a bit and do some more Tangleroot slayers (I still have another 700 kills to do to finish it off).
I'll start that up tonight after I finish up my work for today (damn real jobs, hehe).
