Yeah, most of us don't play at Theoretical Optimization level bullshit. While irritating, the blatantly lulzbroken stuff has never been the biggest issue, simply because they don't happen in real games.
They don't happen in 3.5 games because the DMs don't allow it for being too strong. Simple as that.
If you consider that something on PF is too strong for casters, then you're completely free to nerf/ban it, just as 3.5 groups have banned wish/shapechange/gate/many others shenigans for years now.
PF buffed casters at the other, actual acceptable levels of optimization. And I would argue Paragon Surge, especially once you can Spell Perfection it for free quicken, rivals those shenanigans from 3E anyway. Cast all the spells! On the fly!
Already doable in 3.5.
While it was difficult to play a noncaster in a mildly-optimized campaign in 3.5, PF is making it outright pointless by printing abilities that make it trivial to replace/negate the noncasters and nerfing their few good tricks.
You're totally right! PF druids rock on with Wildshape and magebred fleshrakers! Oh wait, they don't. Wildshape got nerfed, and druids no longer get super pets that get buffed for free every couple years.
PF mages pick Incantrix! Shadowcraft mage! Initiate of the sevenfold veil! Initiate of Mystra! Planar sheperd! With reserves of strength and earth power and divine metamagic and oh my, nope, just kidding. None of that in PF. And yes I had players requesting to use all of that over my many years as DM, and also saw groups using those (or at least gloating about having used those).
Playing noncasters in a "mildly-optimized" campaign in 3.5 already was pointless, it was just that DMs got used to hax down caster options and/or buff noncasters themselves to make it at least resemble like a fair game (or many times they just didn't care, or the caster focused on support, or whatever).
Really, please stop pretending that the zillion online guides about 3.5 caster tricks and combos suddenly disappeared. They're still there. They're still mostly on a completely diferent level than PF mages. And PF noncasters still can kill stuff that's vulnerable to HP damage with pointy sticks, which is what 3.5 noncasters were doing all along whitout houserule support or ToB.
