First let me say im new to MMO's in general so im looking for clarity on what people are actually looking for when they use phrases such as:-

We want to solo/play by themselves.
We dont want to dependent on others
Dont introduce skills caps etc as this will hurt solo players and make them leave etc etc

Like i said im new to MMO's and the reason i got into it was the player interaction because thats what i thought it was all about.

Are solo players looking for a fully downloadable version with an offline switch so they can enjoy the world on their own?
The phrases about them leaving, would that actually hurt the ingame content anyway as u wouldnt know they were there anyway cos they dont want to interact/trade? (ofcourse it would hit the developers financially).
Or do they only want to solo to a certain amount 95% solo 5% interaction or you would like to play your game and use chat only?

I think ive got a grip of the crafters vs PvP senario, but was looking for a solo players understanding any input would be appreciated so i can understand more.
