Also from my experience I would recommend directbet.
If only directbet offered esports I would recommend them too bad they don't and probably will never add them.Afaik back then some users already suggested it to michelle (directbet's forum rep) and I think they said they'll consider adding it in the future.
Yes I saw some rumors about it as well. First time I saw it, was in their competition. Some users were asking and they said they were planning that.
It was a long time ago, don't know if that is on top of their list or not.
