This thread reminds of the ones from 2007 when Gianthold was released. Then, people complained that casters were over-powered because of Finger of Death; casters insta-killed everything.
You know what Turbine did? They listened to the people crying and added Deathblock type effects in upper level quests.
For the record, I do not see what Matt and several others are stating. I think it is ridiculous to think the average caster has TR'd at least once (I am just finishing my TR and I am vowing to never do it again because it is so boring) from Wizard for the Wizard Past-Life active feat. I also don't do the easy epic quests like the House D, House J, or the VoN pre-quests; I mostly stick to ERed Fens, EChrono, EDQ2, and EVoN6.
I just don't see it. I don't believe this is as frequent as several people are stating.
