Expectation vs Reality
When the system was coming out, we were told that loot would include champ shards AND blue essence. Now that friends of mine are finally hitting 31+, I'm finding out it's champ shards OR blue essence - only both if you want to lose out on some of both. That's... Lame.
As far as these systems go, HotS has one that is far superior, and it's also a game I enjoy as much as I enjoy LoL. But now that rewards in LoL are no longer, well... Rewarding, I'm feeling like I'm losing reasons to play this over HotS.
I don't just want quick, free shit. I never did. Hell, I've spent many hours on this game over many accounts, and I've spent hundreds of dollars on all sorts of things in-game. But now I feel like I HAVE to buy the things I want, because my chance of getting them through just play is so incredibly abysmal that it's a chore to play, not a fun time, for me.
I really hope this system is looked at and revised soon. I love this game, and I'd like to keep spending hours and money on it without feeling bad about it. Right now things just don't feel fun.
