1] and 3] point is the same
I don't know why do you want so desperately stop PLers. Are they flooding our community? Your RP is spoiled no matter where you go? As far as i know we do not RP with people who don't want RP, we don't talk with them, as we are supposed to talk only when we RP and as we don't RP with them, there is almost no reason to speak with PLers. So why do you worry so much about them? Besides, IMHO, you may be suprised, but they don't feel very comfortable when they finds out that they are not the main power in PS and Devs, GMs and everybody else who has somethink to say, are against them. They eighter has enough after a while and leave. Or stay and don't really disturbs us, even if they have high stats and skills.
To people who RP a lot and train much less:
Then i suppose you are RPing someone who isn't really skilled in fighting, crafting or mining? If you never spent enough time on training, you can never call yourself a good warrior. If you didn't craft enough, you cant be good crafter. If you don't spent time in a mine everytime you are online, you can't be a good miner.
And you can still RP while doing all this. But if you RP somethink else most of the time, why do you RP your character to be someone else than what he does?
You start with character who barely knows somethink, so you can't be anybody, you are restricted.
Also, your char may be someone basing on your real limits. I mean... I will never play aristocrat character, because i don't know how to do it well. People with not enough time can't have ulbernaut slayer.
We all have our limits in this or other form.
Point 2]
Your idea only slow the process. If you stay at side and look at everything you won't really bother about individuals. It won't matter for you how long did it take to some people to reach some skill rank. You will care about having both trained and untrained in the character base. And as i said, you are only slowing the process, people will still learn multiple skills, but it will take them a year instead of 4 months.
You encourage specialisation instead of enforce.
If you really look at all of our ideas, you will realize that it's not a way to slow down the entire process of leveling; it's just a way to keep leveling within a reasonable amount. It's not like it takes a ridiculous amount of time to regain the points needed to level. THe real point is just to kepp people from getting more than 50 levels in a very short amount of time.
And if you say that the roleplay value wouldn't get any better, than I'm afraid that you are wrong. If people can only train so much withing a certain time, then they will have to make use of the rest of there time. There are a few different things they could do:
1. Sit around and mope about really wanting to train
2. Go off and fight monsters
or
3.Role Play
This means that a large goup of people who wouldn't normally consider roleplaying will pretty much have to, and if they don't like it, good, we don't want them around anyway.
