Allowing all access from the phone

I believe that if all pc features are added to the phone.It would be more easier.I'm a new player and I'm mostly in my phone rather than pc. I can't even attack others from my phone

They've actually said that they're working towards this, and it's their biggest goal right now.

How long might that probably take?

Probably years. This game isn't big enough to afford a full-time dev team.
