Horde: Tauren Druid > DK/Pala Ally: Druid/DK/pala I think, cuz druid has instant fly + no leave fly mount so they should be equal or possibly better than dk pala on ally. druid is obvoius best on horde.
The best is any kind of druid with the Forager's Gloves It gives tauren-like bonus for Herbalism and 1.5sec cast cut off Mining too.
the best is still a druid, doesnt matter gloves or not, assuming dk and paala gatherer will get the gloves..
Ofcourse best race is tauren, for the fast herb picking. About class? Druid use its instant-fly bonus only when picking the node. Pala/DK when they're flying. => The more node/h you have, the better the druid is. The exact treshold is at 18 seconds*. If you fly longer than 18 seconds between nodes, DK/pala is better => If you're getting more than 199.9... nodes/h, druid is better. Lower than 199.9... pala/DK is better. *You can calculate it like this: Car A (druid) departs from point N by 451 km/h (451% flying speed) Car B (DK) departs from point N by 492% km/h 1.5 seconds after car A. (DK had to mount) What time does it take for car B to catch up Car A? = 18 seconds. That's theory, not counting in HB lags, combat, node spawns... (lets say both test subjects fight same time and have same node spawns in our test) But the bigger the difference from 200 N/h, the better or worse druid or DK is, no matter the fights, lags... and of course flying to mailbox is the biggest advantage of DK/pala. My favorite is DK tauren female. Because DKs start at 55 and can smash things down quite fast, taurens are fast at herbs, and females are smaller = less stucks around the corners. For alliance, I'd go with draenei DK, because Draeneis have pocket selfheal and 1% hit. There's not really any gamebreaking racial for farmers on ally side. just my 2 cents
Druid saves a ton of time in mounting as has been said. Other than that DK's are good mules if you don't like playing them.
wrong canculator druid can avoid many combat -.- DK/pally cant . let me count with my routine , DK got around 60kill/h druid ~ 15 kill/h , that mean DK take 45 more combat . DK need 15s per combat . same with druid ( green gear ) = DK lost 675s incombat > 11 min with medium routine , 150 o/h , i can count DK lost 675/150 = 4,5s to combat per node . Car A (druid) departs from point N by 451 km/h (451% flying speed) Car B (DK) departs from point N by 492% km/h 6 seconds ( 1,5s mount + 4,5s combat ) after car A. (DK had to mount) What time does it take for car B to catch up Car A? = 66 s . The exact treshold is at 66 seconds , not 18s . that mean druid win , in every count -.- i dont count lag , because with lag , everyone lose . if you can burst mobs in 5s ( very good gear , kill mobs in jade forest ) The exact treshold is at 36 seconds , not 18s . if more than 100o/h , druid win . less than 100 o/h , DK win . but with farmer , druid win .
There's a lot more variable we both don't count with. For example our druid could be non-tauren withour foragers gloves, that means for every herb he land, he'll aggro same mobs as DK, and because he's not fast enought at picking the herb, he have to figh like DK would have to. 18 seconds is in ideal condition, where you don't fight at all. Your druid will have to be set up right to don't fight on aggroing mobs. Or your druid may be only miner, so he have to fight on every aggroing like DK... Or you may have awesome profile, where you don't fight at all (my DK have 16kills/h right now, after 3h18min) It's just a theory!
just a theory , but need canculator for most people . and config for druid avoid combat is a cake . btw , i think you need keep your mind , just use DK and pally , that better for me )
