Here is my little Review.
I for one, Hate WoW PVP, Hate most MMO PVP in general except when it's the source of gameplay(IE: Darkfall Online, Shadowbane, UO). I've also hated just about any MOBA i've tried from LoL , to Dota, even the Mobile Heroes of chaos(or whatever it's called). I play WoW , raid 2 nights a week, and with all my other projects, try to fit some other games into the mix when I can. Have been a general Blizzard fan, but wasn't a die hard SC player or Diablo Player. So I've strictly been only a WoW player since the RTS and on and off through WoW itself. My friend hits me up that Heroes is off closed beta and I should download it. I humor him and hit download and tell him I'll try it sometime. Next night hits and I figure I might as well fire the game up. Sign in, do the tutorial, get to the main screen. My friend jumps on and says, let's do some games together!
So I start trying to figure it out, there's a weekly rotation of heroes to play for free, your levels persist even after the free week. There are 2 sets of levels, player and character. Each with it's own goodies. It is F2P with heroes, mounts, and skins being purchasable for money and most stuff being purchasable with in game gold. Most games last about 15-30 minutes each.
After about 30 minutes into the actual play. I have to admit. I was hooked. I'm not sure why either, as I'm usually a , let's make the game harder type of guy. But HOTS took all the extra junk that I hated from other MOBA's and made it that much cleaner. Granted the game will not appeal to any die hard MOBA player probably but for us casual MOBA players. It's perfect.
So, so far I've enjoyed it. Besides wow it's been my main game on off nights. I'm also on the hearthstone bus, but more so when I'm stuck somewhere with my phone. I would definitely give it a 2-3 game try. If it still doesn't appeal to you then it probably won't.
