Maesyn
Took Maesyn to Hinterlands for various quests: trolls, troll altar, griffin eggs, slimes. Hiterlands is quite a nice little quest hub, there was enough there for 45->46. The fights against level 48 slimes were more challenging and a chance to practise bear skills which are slowly improving.
Dinged 46 and went to class trainer. Somehow I had missed some next ranks at level 44, I may have only looked at those in the first talent tree as she got some nice updates to feral combat (pounce, rip etc). This may explain why at 44 she was struggling with those naga.
Went back to the naga cave and it was much easier, two levels higher meant a lot less threat generated. Mission accomplished.
Did the quests that involve running up and down the Feralas shore for a hour killing water sprites and minaturised giants, level 47-49 mobs (me 46). Maexyn had also done this at 46 and it was easy for her but Maesyn found it harder. The 49's were tough but doable and needed healing pretty much between every fight. Any adds were dealt with by running away, Maexyn would have taken them (banish ftw). Towards the end it was downright boring. Went to Tanaris and knocked off one of the 'wanted poster' quests. Killed a 46 with two stealthed 43s. Started in bear mode and coped admirably, even remembered the barkskin spell for a handy 100% healing touch. In hindsight I should have done a regenerate while barkskinned and in caster form but hindsight always makes you look a noob.
Quest turnins plus a couple of hyenas and ding, level 47. The dwarves in Searing Gorge couple be next to develop my bear skills before tackling the Pirates of Tanaris.
I have most of the useful Feral talents maxed out right now and I'm only still spending points there for the tree-defining Mangle talent at level 50. The other talents available are silly +1% things that don't seem worth it. In hindsight, keeping some points in Furor, Naturalist etc would have been better with a respec to Mangle at level 50. The Feral Kitty isn't quite as awesome a farming machine as it was back in the thirties, I think that balancing is coming into play and getting mangle at 50 will restore the status quo.
I would upgrade her gear but OMG WTF has happened to the price of greens in the AH? Nothing there under 10g! Everyone is levelling an enchanter ready for wotlk 
Maezyn had just two leathercrafting recipies that were useful for a 40's druid, level 41 boots (with +1 stealth) and 48 bracers Maesyn is only just getting into skinning rugged leather which will mean Maezyn can craft half-decent greens for Maexyn to get the mats to level her enchanting beyond 277... it's all very complicated.
Peter's Moblog
Cat form druids are awesome for farming because they have such high dps you kill fast. It may be your gear thats not letting you kill as fast. Your talent tree may also not be specced right. Go to wowarmory.com and look up gasmaskk...click the 70 feral druid on alliance korgath adn check out my talent tree. That tree is what you will need to get the best results out of feral spec. Anyways one of the best way you can kill any mob with feral is to tigers fury/ravage them then claw/mangle away till full combo points then ferocious bite..Any other questions just email. Also can help with Ret pallys, combat rogues.
