Goodbye LoL. I'm playing Heroes of the Storm from now on.
I just picked up HotS recently. What a much better game it is, at least for me!
-Characters are far more interesting. If it's one thing I despise about LoL, it's that the champions are too generic. A lot of them couldn't get anymore complex than "you use Q as a skillshot poke, W as a steroid or another damage, E as an escape or CC, and R as a finisher." In HotS you have very interesting characters, like one that can act as a symbiote for one of your allies. That's something that LoL has never explored, even after 120 champions that have been released.
Most importantly though, no items. This means no last hitting, and no such thing as one enemy being "fed". I LOVE this. This means that turn-around plays are much easier to do, and something as small as taking a mercenary camp can dictate whether you win or lose the game no matter how far you are. One thing I hate about LoL is that if one of your enemy carry gets fed, there is really NOTHING you can do.
Don't get me wrong,t here are "carry"-based characters in HotS that are labelled as "assassins". But they won't be able to 1v5 your team.
