Hello. A bit rant time, but I stand behind every word I say.
So........let me get this straight. A pure wizard, with 3 wizard past live feats, 3 FvS past life feats, taking +3 sp in enchantments, taking both sp feats,having heighest possible sp item and +3sp from ED would have excatly 50% chance at landing a spell at the lowest level drow there is (and im talking about drow warriors and archers, not drow pristesses). Breakdown:
20lvl
+4 both feats
+3 AM sp
+3 ED
+6pl wiz
+3pl FvS
+3sp item
=42sp max at lvl 20?
So a fully maxed sp wizard needs to roll a 10 to pass drow SR in first EE encounters (ES 1 chain). Im talking about drow warriors and drow archers btw, not the priest.
Some people might say: well that's what you get for going in lvl 21 EE quests with a lvl 20 wizard. I say to them: How to hell to reach lvl 25, and how come all other classes dont have any problems in EE's as lvl 20 (did 15 or so EE lives, most of them solo)? Even at lvl 25, I would have 75% chance to land a spell as a totally maxed out SP wizard (good luck everyone that doesnt have 3 FvS and 3 wiz past lives. Or gods forbid that you aren't pure wizard).
Im curious, what's the SR of enemies in tempest spine? I couldn't find any info. I went to check youtube and search for a LE runs that has a wizard in it. I found non. No wizards at all in LE tempest spine or LE HoX. Full raids.

To conclude, good job turbine for making wizard a worst CC class (and I challenge anyone to try a class that has worse CC capabilites then a wizard in EE). Now let's see some solutions:
Stunning blow breakdown at lvl 30:
10 (base)
+12 (boots of the innocent)
+2capstone
+3fig pl
+6 insigniful combat mastery
+6 LD
+3 race
+4 legendary feat
+2tactican
+20 feat
+15know the angles - I took 40 int which is easly reachable (15item+7tome+2ship+11starting+7insig is 40. with 11 starting only).
+35 str - I took only 80 str at lvl 30 which is a joke
=118 DC of stunning blow and I only took 80 str (probably all str builds have 80 str at lvl 30)
I left tons of things here, like psionic str, madstone, ofcourse didnt add cookies, pots, bard songs etc. I didn't even add the epic destiny str or str on level ups. This number can go up easly, I'm really far from max achivable stunning blow DC. Not to mention some tactical feats have higher base or they add character level to.
So here is my suggestion to make wizards a CC class. Give end game mobs 118 tactical feat saves (to casters and archers, melee mobs should have 130), and remove no save tactical feats. Let's see how would those nerve venom spammers, 1st life tacticians with lvl 11 gear and no save CCers feel then.
Or you could finally fix dispel and fix/remove spell resistance.
P.S. I'm quite sure you forgot that all DnD games that were ever made had a spell that lowers spell resistance. Where is it?
Oh and, does anyone in DDO actually bother to go over 120 tactical DC? I still find it funny how wizards are trying to increase their DC's and spell penetraitons like there is no tomorrow and melees barely get half of max possible tactical feat DC and they are good to go. Great balanced stuff right here.
