War Within Tier List(Fun)?

To those that played the beta, what specs/hero talent setups felt the most fun to you? I haven’t been following along with the updates and I wanna check out what feels FUN vs what is meta or whatever

I gravitate toward casters and frost and fire mage feel good. Playing with either hero spec is fun as well. Frostfire bolt looks too good not to use. Other than that Demo warlock was a blast with a small army of demons in tow.
