If you're not specializing in pushes and forcing attacks, then does bonuses to pushing and forced attacks actually matter? No. But that extra defense DOES.
You're focusing a lot on the enchanter. There are several other schools... not only that, but the mage gets the benefit of several school bonuses, not just one.
Int/Wis isn't exactly hard to come by.
Erm, I just said it is... how many races have an int/wis stat bonus? I can only think of two off the top of my head.
That's an unfair comparison. Comparing the mage to one build of wizard is deceiving. Both the mage and the arcanist have the same requirement for attributes. But an invoker and a staff wizard are equally as beholden to constitution.
Deceiving? Whom am I deceiving? Orbizard is really the only effective wizard build. You can have blasters, sure, but there are better blaster classes out there.
If you're going for (you suck, save ends) abilities, there's Sleep, Deep Slumber, Legion's Hold right there off the top of my head, which is three encounters reduced to nothing by the Orbizard builds.
Ok, well, like I said, it's been a long time since I've actually looked into it all so it seems they've gotten a bit more effectiveness. I don't actually see that as a good thing given that, even after the nerf, stunlocking still exists and is retarded.
If, and ONLY if, you specialize in a type of effect supported by your schools. If you're looking to generalize, the school bonuses only help one or two of your powers at best, and that's not going to help you as much as, say, Staff of Defense, which is always on. Or Tome of Readiness, which is versatile as hell.
Again, the mage gets the benefit of several school bonuses, not just one. And again, I suspect that all schools are eventually going to be represented on all spells, giving the mage player a much greater variety of choice with spells that are affected by their school bonuses.
And, again, the mage not only gets to swap out their encounter powers, but they eventually can put EVERY spell in their spellbooks. Forget every other class feature, that alone puts the mage way over the wizard in terms of versatility, and in this game versatility = power.
As well, mage schools have no feat support, whereas wizard implement mastery does.
We both know they will eventually have feat support. It's just a matter of time.
The comparison is not as simple as you make it out to be.
Nor is it as complex as you make it out to be.
I have a big one. Ritual caster. Mages don't get it.
I'll happily forgo a benefit that sees little to no use in any game I've ever run or played in, for even the weakest benefit of the mage.
