I would support this if it was capped at 50 or 70, but even if so I would also want a refund for the 1 year subscription I have.
(Since all my skills are under 70 I would simply continue playing for "free" after a one time fee).
Already, I can see this is flawed as I have paid at least 2 years subscription already.
There is no way I would pay £80 for 70 cap on my skills, especially if they were then reduced skill gain for not being prem.
If they are not reduced by not being prem then there is no reason for the vast majority of people to go prem to build deeds etc.. (70 skill is enough) so the game will lose out in the long run.
My question is though... if you're not premium what do you want to do with your time in wurm? Do you really need 70 skill to do those things?
The kind of situation this seems to address, in my opinion, is what Wurm Unlimited is there for.
The "price" you would need to set this to get the community to accept it, would be more than a years subscription, so if a player "won't pay £10" to continue playing after a month, why would they fork this out?
I agree that the game is almost not worth playing without premium, but its really not that expensive, especially when you can pay in game.
(If you're at 20 skill to care about this thread you can easily make the silver in game).
Besides, I'm fairly sure the "non-prem" option is meant as a trial period/try before you buy. Not as a long term "stick around and play for free".
