I tried Heroes of the Storm and it's depressingly bad.
Seems like blizzard is intentionally ignoring every issue people have had designing characters in the MOBA genre. More than half the abilities in the game are point-and-click. Most bruisers and tanks play exactly like Taric: heal ability, point-and-click stun, mindless autoing. Imagine playing a game of League without anyone buying items and with 3-4 Tarics on each team with an ADC or assassin. That's how HotS plays.
It's just...goddamn. I was sort of looking forward to trying it and it flows worse than when LoL was first released. The engine's amazing and totally destroys League's, but the gameplay and balance is so bad that I can't see myself or anyone who enjoys MOBAs ever prefering it to League or DotA.
