A lot of the ideas that are being tossed around on this thread sounds good and seems to becoming not so complicated as the idea grows. I think something similar to this could probably work if hosted servers required people to get gold to develop on them or maybe at least silver?
It might give incentive to people who normally wouldn't upgrade to upgrade to develop on a server. Plus having a few more servers for people to play on could be nice but could have a few cons who knows? The problem with this idea is that if trials got unlimited access to hosted then everyone would just make a trial account to play those servers right? And would people with unlimited classic get access to hosted too? I probably didn't read over everything but oh well =P
Anyhow it could give incentive for trials to buy gold if they like how graal works =0.
