I haven’t tried HoN yet. Could’ve gotten a key when it first came out cuz my friend had me submit a request with his email (his IP was blocked for a while cuz he requested a bunch for his friends), but I didn’t think of it at the time. 
I’ve heard some people on the forums calling it inferior to LoL, but people are threatening to switch over to it after last week’s patch. I’m still addicted to LoL, though; I didn’t mind the patch.
Can you PM me a key? I’d like to give it a try.
