If there's no pet I most likely will not get a virtual ticket. So I do hope there will be one, since after watching the last two years' streams I ended up a fan of both 3v3 arena and hearthstone tournaments. I don't participate in either (PVP or hearthstone) but for some reason I love to watch!
I think it's because you don't play either that they are more fun to watch, if that makes sense. I don't like playing Overwatch, but I do like watching the occasional Youtube video. Likewise, hockey is the only sport I can't play, and the only sport I watch on TV. I think for some people, if you do it, it's same old same old, but if you don't, you get a new perspective watching and can really enjoy it as opposed to playing it.
Very likely. I thought I'd like raid/dungeon race type videos better, but because raiding is what I do, turns out that I really see no reason to watch people doing what I already do poorly for hours.
Granted, high end players are far more organized so watching their coordination is one thing that does impress and appeal to me.
In the same vein I think it's the extreme coordination required for high ranked arena play that I find exciting, though I find it boring when half the teams are rogue-mage-druid lol.
I only started watching Hearthstone videos because it's what my spouse likes playing (funny that you mentioned hockey, it's because of him that I watch hockey), and I was trying to understand the strategy and such behind the game. It's actually pretty fascinating.
Since I'm way off topic now I'll add this: if there was such a thing as a Blizzcon PVP pet battle tournament or something, I don't know if I'd watch. I'd give it a go, but if it was all mirror comps and strategies I don't know if it would be terribly interesting.
