Lol cool card mount. Is lvl 12 a fair bit of playing? I havent touched it yet so im unsure.
I played it sporadically over the last 4 or 5 months. I logged on to see my account level half-way through 9 a couple days ago, and played a bit more since and am already half-way through 11. It doesn't take that long, but it is a bit of a grind. I bought a lot of characters with gold and real money a bunch of months back, so I'm able to keep it fresh somewhat (also just bought Sylvannas and Kael'Thalas yesterday). You can buy stimpacks which will increase experience experience gained by 100% and gold gain by 150%. I think it's $3.99 for a 7-day stimpack, which should be more than enough to get you to 12 and save quite a bit of time. You get an automatic 7-day stimpack for hitting level 10 (I just found this out yesterday).
I've never really played MOBAs, so I don't have anything to compare it to, but I have fun with Heroes of the Storm. I'm drawn to the Warcraft lore in particular, so it's really fun to control characters like Thrall, Sylvannas, Kael'Thalas, Arthas, Jaina, Uther, Malfurion, etc. Sylvannas does so much fucking damage..
EDIT -- I forgot that you also get a 50% experience bonus for playing with a friend. I'm close to 12 already, but if you (or anybody) needs somebody to play with to get the bonus, hit me up -- #Soilwork1642
