I was over on test server and leveled my TR'd Wizard to 25 and capped all his EDs. With a 36 int and a few decent buffs he's sitting at a 42 DC.
This is what he had endgame before TRing at Heroic 20.
Granted he only has a +2 tome and Int 6 gear, but he is ED capped and at 25 and sporting an Enchantment Mastery item as well as Archmage Enchanter.
The problem is, a +5 tome and exceptional gear, plus a +8 Int item and +3 ench master item would add 7 to this DC as well as a ship buff I missed on test server bringing him to a 50 DC for endgame with the best gear available.
I am trying to get a sense for whether or not this DC is effective or not on EE. On EN and EH 42 is not exactly reliable and in higher level content it is almost completely ineffective (Lords of Dust EH approx 50% success from testing). If it's not usable for EE I am going to have to convert him into something else and explore other build ideas. I do enjoy leveling an enchanter, but I can't see investing that much time into something that won't be able to contribute in a significant way to endgame.
