I am by no means the world's greatest druid having only played up to around 2100 and not having much playtime with my druid this season beyond 10 games a week (darn RL!), but there seems to be a lot of misleading and just plain wrong information in eetkrewgoosejimmi's post. His ideas and impressions of the class and team match ups seem to be solely based on low level, low coordination play.
"you never have to worry about mage healer teams, as they are horrible" Actually mage/disc is a viable setup and completely counters druid/warrior. If you play a competent mage/disc you will simply never kill either of them, and they will eventually kill you, although it may take hours. They will set up a kill shot once every three minutes or so when all their cool downs are up. Check out
YO GC WHERES MYGBANK DOG and
MAGE PRIEST LOLWUT for some of the more well known mage/disc teams.
"Warlocks. Obv with a healer team, the warrior is almost always on the healer" Against well played warlock/druid teams this can set you pretty far back. Enemy druid just drags your warrior away from you and begins an endless CC rotation. The warrior is doing close to 0 damage while the lock is free to run amok with dots on both the warrior and you. One deathcoil away from a pillar followed by spam fear + drain mana while your warrior is sitting in cyclone/roots and all the sudden you are 3000 mana behind and their druid is drinking.
A more viable strategy is for your warrior to target swap a lot to create pressure on the druid that way. Build rage on the warlock, quick swap to the pet (druid has to freak out and starting healing a 0 res low HP target that may be out of LOS) then a strong swap to the druid. This way the druid is burning a lot of mana throwing hots up on 3 different targets and eventually you should probably get a kill shot on either the druid or the pet.
"More often then not i'll have a rogue on me, and its quite laughable actually" Rogues are extremely dangerous in almost every team flavor they come in. Spriest / rogue is extremely difficult if they play well, Rogue / Restokin will be a difficult uphill fight for druid / warrior, as will mage / rogue and to some extent warlock / rogue. You can win these fights but they are most certainly not "laughable".
"if he is marks his pet will go down extremely fast. Ive moonfire killed a pet, in 3 casts... while pole dancing" This is just plain misinformation. Killing a pet against hunter / druid will be difficult if the hunter is well played and knows how to micro manage his pet. And it will certainly take more than 800 damage from three moonfires to do it. And even when you do they will laugh in your face as your warrior is scattered into a trap while you are cycloned and they resummon the pet in 4 seconds.
I don't mean to trash your post, its obvious you put some effort into it and people willing to help others out by spreading some knowledge is a good thing. I'm just afraid that aspiring druids are going to take this post and read it as gospel (OMG it was on EJ!) when there is a large amount of of both incorrect and misleading statements and strategies contained in it.
My advice to all druids is, yes, read all these ideas that people post but in the end you have to take them with a grain of salt. You are only going to get better by experience and playing a lot of arena, during the course of which you will figure out your own approaches and strategies to match ups. After each match try to examine when things started to go wrong. (Well, when the priest was able to fear me and start landing mana burns, the momentum of the match really changed. Next time I will call when the priest is peeling twords me so you can intercept him and get him re hamstrung.) Just play play play and don't get raged when you lose in the beginning, it'll take some time to work out coordination and team strategies.
