Hearthstone Arena Data after 700 matches

After 700 Hearthstone arena matches, I've had my ups and downs, but here are the black and white stats:

matches	wins	win %
700	432	61.71%

Well that isn't too enlightening, so let's break it down by what class I played:

my class	matches	wins as	win %
mage	108	72	66.67%
rogue	75	49	65.33%
hunter	55	35	63.64%
warrior	49	31	63.27%
paladin	140	87	62.14%
druid	125	77	61.60%
priest	55	33	60.00%
shaman	51	27	52.94%
warlock	42	21	50.00%

Some of those are still subject to small sample size fluctuations, but I've done at least six arena runs as each. Clearly, I have a favored triad between Mage, Druid and Paladin. Each of those three I have played at least 12 runs, and while Mage backs up this preference with performance, Paladin and Druid are decidedly average. 

On the other side, I have no more than 9 runs with Rogue, Hunter, Warrior, Priest, Shaman, or Warlock. Don't ask me about how to play Warlock or Shaman, because I clearly don't have the answers. My style is to always clear the board and grind my opponent out of cards, trading life for time. That is almost certainly why I don't like Warlock, where the card quality is low and the pilot can trade life for cards at any time. Why then is my Shaman terrible? I truly don't know.

But this is only one side of the equation, let's also examine my performance from the other side of the table:

villain's class	matches	wins against	win %
warrior	69	50	72.46%
priest	47	32	68.09%
rogue	52	35	67.31%
warlock	46	30	65.22%
shaman	82	52	63.41%
paladin	114	68	59.65%
hunter	69	41	59.42%
mage	143	81	56.64%
druid	78	43	55.13%

This table tells us a few things: 

1. Mage is the most popular class, and seems correctly rumored to be strongest. My Mage win percentage is 67% and I am only 57% against. Shockingly, my overall is 62%.
2. My "grind out an advantage" strategy is weak to mass removal (Mage & Druid), as well as direct damage (Hunter).
3. Priest, Rogue, and Warlock lag behind in usage, for good reason.

Since I have played Magic (specifically limited) for so long, I am accustomed to playing one style and I don't think I adjust well to the added wrinkle of different classes playing different styles. This is my challenge to myself and I'll check back in after a few hundred more matches to let you know how the times are changing.
