Spell creation was horrible and over powered. I guess it is different mentalities. Some people like walking through a dungeon insta melting everything they come across while other people such as myself (playing on max difficulty) rather have each encounter be risky and dangerous. When I walk into a room with 3 enemies i'm going to use illusion to turn one of those guys on my side, necromancy to revive whoever dies, alteration to tank, restoration to ward, destruction to do my own damage on the enemy. Using "Just destruction" is like a warrior using "just one handed" (no armor, no shield, no blocking) and complaining that the game is unbalanced when he dies.
You guys that come here with your numbers of raw damage are what we in Eve call..."EFT warriors." You have your fit and on paper it says X Y and Z but in practice things turn out differently. But maybe yes raw damage output wise a warrior does have a higher number. But a warrior is a one tricky pony. Walk up to you, slash away. With magic, destruction alone, you can hit from range, set up rune spells as traps, and most importantly choose specific type of damage depending on who you fight. (frost for warriors, shock for mages, fire for general damage.) If you are just that uncreative that you can only look at raw damage numbers, you're doing it wrong.
"but teh numburz dont liiieeee wahhhh

why cant i kill everyone i meet before my magic bar runs out!

"
Do you know any warrior class that kills everyone before their stamina hits zero?

And with magic you have healing spells that keep you alive and alteration spells you can use to tank that won't slow you down at all. A warrior to be effective has to spend his leveling on both health and stamina. A mage can more or less rely mostly on magic with a little bit of health.
And who the hell is spouting this non sense about "enchanting furthers a warriors DPS even moaarrr

"
Enchanting while it does that is first and foremost a tool for mages to cast spells by way of mundane objects. A mage that can't do jack with a sword or bow suddenly becomes viable through enchanting. Using illusion and enchanting now i can rain death with a bow from afar all without even really dipping into my magic reserves.
So in the end let me get this straight... as a "pure mage" you want to do the raw damage that a warrior does AND be able to summon allies, turn enemies against themselves, go invisible, heal yourself, tank like a bull unencumbered, all while doing your damage from a safe distance? Why don't you just turn on easy mode? Or HTFU.
What about the "pure thief" character? None of the thief skills actually do any damage since archery got moved to warrior. And quite frankly I agree with that. (Using a bow is not some nimble "stealth" based skill but rather something that takes a lot of strength to do. Get yourself a 100 pound bow...classical not the modern stuff they have today and shoot off a few arrows. Mind you 100 pounds is toward the lower end of what was actually used.)
In short character "classes" aren't suppose to be the equivalent of one another or else we'd all be doing the same thing with different animation. It's about using different abilities to approach the same situation in a different manner. You can't just look at the raw damage number and flip out. The lessening requirement for magic is a big big boost allowing you to cast the same spells over and over much cheaper. Honestly though if your way of playing a mage is running in and casting destruction spells at everything you see, well someone that unimaginative probably shouldn't touch magic. Quit wasting the dev's time with this non sense whining and let them fix real issues like bugs and crashes.
