Looking for a Mobile MMORPG

As the title says, Looking for a mobile MMORPG to play on the go. I've seen a few games here adn there, but none that offer the depth of what PC games do. Any suggestions? I've heard of Forsaken World Mobile coming out as well in other threads. Does anybody have any info on this? I'm at work so any info that can be given would be great! :)

Boom Beach is worth-recommended for good gameplay and lots of boom beach strategy to help play better.

"but none that offer the depth of what PC games do" -.-
