Barbarians can get pounce...at level 10. Summoner can get it at 1, though (thread topic, much...?).
Paladin DPR is basically X enemies / day are just plain marked for death, all the others...you have a big sword and PF's version of PA. So you're alright for damage... (X = your # of smite uses/day). Summoner DPR is actually much higher based on that same principle, since he can just keep summoning new minions with Smite much more often than the paladin can use it. And those summons may come in a pack, may have multiple attacks, and/or may have pounce.
Cleric has the same problem as 3E, buff time at start of combat. Dvine Meta Persistent cheese solved it, without that, it was no less a "problem" there than it is in PF now. At least now at higher levels the cleric can take Spell Perfection on his favorite spell and quicken it for free as much as he wants. I have that set up with Divine Power, it's pretty awesome.
Druid definitely got banged up way more than the other casters (largely due to the fact that every other caster except bard was straight up buffed out the ass with cool new shit), but they have several silver linings. Now all equip except armor and shield meld when wildshaped but are still functional! That's awesome! Also, more natural attacks are considered primary now, so you can easily end up with 3+ attacks all at highest BAB and full str to damage. The ability to speak while in wild shape is now codified into a feat (Wild Speech) should you want it. On the other hand, elementals can talk anyway and you gain access to those forms and plant forms (though plant forms ALL suck total freaking ass, seriously) much earlier than in 3E. Hell, you get wildshape earlier and large and huge size at least 2 levels earlier than in 3E! And once you get up to huge size, powerful wildshape feat (count as +1 size for CMB) can give you at least a +2 to all combat maneuver checks, +4 if you can be enlarged and polymorphed simultaneously (I've seen it argued both ways).
Druid is still pretty strong.
EK is fine for what it does, people complain about gishes too much. In the end, a Fighter 1 / Wiz 9 / EK 10 is much weaker than a Wiz 20, but also much stronger than a Fighter 20. Like seriously...what were you expecting? "Whoah, I mixed a weak class with a strong one and ended up with...something in between them in power level... gnarly!" You can even take a trait to recoup the 2 lost spellcasting progression levels (though not the extra spells per day / higher level spells acquired).
The only "problem" it has is that the Magus exists and basically stole its niche. Want to be a warrior with lots of magical backup and attacks/buffing? Just be a magus and blend the two together in the same action! Oh, but you want the advantage of 9th level casting from a much wider spell list...wait, why are you losing 2 CL again?
