Well said Zeltino. If I may add my two cents without sounding like I know more than anyone on these forums do:
With a 900 player average there are bound to be more hackers/cheaters if you will. And since the IPhone server has generally a lot less stuff to do there's more of a need for imagination vs PC servers who have events, npcs and (small) quests. People get bored. I believe this reimagination of Classic was initially meant to be a chat mmo, and Less of a game. Due to the overwhelming growth that happened after Christmas I've noticed a slow transition into a more familiar Graal. I guess it was inevitable.
Due to the low price and the parents who buy their kids iPods and iPhones for Christmas/Birthdays (whatever happened to racecars?), yeah, young people have easier access to it. Does it bother me? Well sometimes... I'm an 80's born and naturally it was difficult to find people I could relate with but you'd be suprised how much of a diversity there really is on there.
I guess we all may have our underlying biases and envys since it's only natural to proclaim what server "is da best server". But if we could all look at this with the glass half full for a minute... We just brought in a new generation of people and a new generation of creativity coming forward.
I can't say too much about the GP process since I'm sort of a new hire but it's not like they hired scripters from iPhone server. That might have been a different situation. The GPs who were already on since December were available to us and left a good impression for us to reflect off of. Just as anyone on pc has seen a GP do what they do (warping, jailing, answering feedback, helping others in general), an iPhone player can catch on pretty fast.
I'd say more but... I'm typing this from my iPod
