Other than the earlier mentioned PS (which is a hell of a survival ability) i would modify some talents as well. As i see the talent tree advised to feral druids is exactly the same as the balance, and that's bad. If i were leveling my druid now, i would use a talent tree something like this
.(using it for questing these days) Wild Charge is more effective, when you go stealth, charge and attack, then the constant speed buff. Cenarion Ward, because you can use it before fight, and it does a decent healing (as of patch 5.2), you don't have to trouble yourself healing up every 1 min. (and you don't really get to too low hp) Basically Typhoon is a balance or resto ability, no use for a feral druid outside of pvp (in pvp only if you have to knock someone off from somewhere, like in Eye of the storm), feral is melee what good does it make to knock someone from melee range? If you need it to escape from mobs, use Mass Entanglement, its much more effective and easier to use. Finally Force of Nature is pretty much useless, it can be considered better for leveling, because it has shorter cd, but if you need this to simply kill mobs, than you do something wrong. If you want more constant dmg, than use Soul of the Forrest, otherwise use Incarnation. Use this to finish up mobs fast or even to escape from them, if they don't leave a dot on you, than you can just simply go to stealth and run.
@Meowmonster: outside of dungeons and raids you can't really use shred (unless you quest in group with a tank), so to say always use shred only good for scaring newbies off, because they think they do something wrong, that's why they cant use shred always.
