The problem with PC games coming to phones is that most developers won't have the know-how, inclination or resources to develop two completely different iterations of the same game - which is what you'd need to do in most cases dealing with "complex" RPG/strategy games.
So, you'll end up with a game that's adaptable for the limitations of the phone - just like you end up with multiplatform games designed around the limitations of consoles.
I know a lot of people still don't realise that console limitations have been one of the primary limiting factors barring true evolution in the PC segment - but I consider it a fact as plain as day.
So, unless this game was always envisioned as a "light" game adaptable easily to phones and tablets - there's no way around it being a watered down version of what could have been. Well, that, or they'll cancel the phone version.
Now, if you don't mind supporting that sort of development - all of the above obviously isn't a problem FOR YOU - but it should be possible to appreciate why some of us aren't crazy about putting money into the hands of people who don't seem to care about taking games forward like we'd want them to.
joxer might not have the most nuanced take on this issue - but I think I get where he's coming from.
