Is heighten worthwhile in endgame?

[Riorik]

More than worthwhile, it's pretty much required.
The same thing can be said for Quicken...although that can sometimes be worked around but it makes it harder.

Heighten is great end-game.
It's nice on FoD.
It's better on FtS.
It's great on Web.
It's really awesome on SLA hypnotism. (for ench-archmage, like the OP).

Cheers,

level 1 spell hypnotize, heightened, and level 3 spell halt undead, heightened, will get your party easily through almost all quests..all the way to cap

A short list of spells I frequently cast for which Heighten helps:
2. Web, Ooze Puppet (not frequent I suppose)
3. Suggestion
4. Death Aura, Negative Energy Burst
5. Cloudkill, Symbol of Pain
6. Mass Suggestion, Flesh to Stone
7. Finger of Death, Delayed Blast Fireball, Otto's Sphere of Dancing

That's a lot of spells, some of which are pretty key in real endgame content (level 19+ quests; epics and raids).

Yeah, I wail single mob, (it cost the same as heighten fod) but more oftem, I hold them.
I find web useable only on caster types mobs, and I still think that Otto's Irresistible Dance is beter at them than web, because there is no save at all. There quite long cooldown on this spell, I admit, but I've never seen more than 2 casters with high will saves, and second one gets hit with epic big top. Yeah, I know that not everyone got EBT, but notice, that I never said that heighten is useless, I just said that I'm doing fine without it. There is no feat IMO, which is mandatory for anyone.

well, i suppose if you never meet a single epic drow, you might continue on thinking that way.

but personally, from my perspective (admittedly this is mostly on my sorcerer): you can have my heighten feat when you pry it out of my cold, dead hands. there is no way i would ever even consider dropping heighten, it's simply too powerful. the stuff i want to do is all about having the maximum possible DC, and boosting my DC by even 1 or 2 points is powerful enough, boosting it by 7, well... let's consider. pretty much every wizard in existence should be taking some spell focus feat or another. 1 feat is worth boosting 1 category of spells DC by 1 point. heighten lets you boost every level 8 and lower spell with a save DC that you have, and it lets you boost them in some cases by many points (as much as 8). heighten is an extremely powerful and versatile feat, and having it available for spells like hypnotism, web, and even dancing sphere, is well worth the cost.

I took heighten a level 10.
An that felt like to long to wait.

Heighten isn't needed for leveling. You can Firewall and Ice Storm your way to 20. Or if you're a Pale Master, you start Wailing once you're 17 and don't look back.

Heighten is mostly for elite/epic where DCs matter more, or if you're addicted to using Web (+7 DC). For example, +2 DC for Otto's Dancing Ball and Flesh to Stone is noticeable on elite and epic.

I currently have a Lvl 11 AM Drow Enchantment main spec'ed,Evocation secondary. I took heighten fairly early assuming that it would help with CC DC's, but so far i haven't really needed it. I have been looking at a lot of different enchanter AM's and don't really see heighten chosen that often. I'm wondering if i should switch it out for quicken, which i had not really considered as warranting a feat slot over heighten initially. I do plan on taking this toon into epics later on, so i'd like peoples opinion on which feat is more usefull

Heighten is much more useful than quicken for CC. It's not really worth taking at lower levels tho.
