Okay, some points to point out...
If things somehow change and caps will be cheaper/free/whatever number of caps will rise, that goes without doubt. But with that, also good RPers that dont have access to caps will emerge.
Really, you think that those cca 4 days of trading help new players get a grasp at RP. Sorry but i cant just take that seriously. I made about 100 millions in last 2 days (what a waste of time i could spend RPing Q_Q) and all RP i got from that was:
"Greetings" x 10
Some other lines x 3
Even though i announced my presence in every system i visited.
Really, this "Make caps expensive so newcomers can learn" is just a poor joke and all it does is to stop players that actually can RP as they should but dont have that much time.
Look at this this way, i can play a mute character. And for all i care, i dont have to write a line in days...
Do i add to RP environment then? No. Do i still make the same amount of cash? Yes. Even when pirate stops me and asks for money, i can just pay and he will let me go... thats it... without a single word.
Edit: Also... some of us actually enjoy benig a trader or miner... or even a pirate just for the fun of it... I have several independent pirate characters and i hardly ask anything from traders. Why? Cuz most of them are afraid and tries to run given even the smallest chance which my characters enjoy so much. And others? They want to RP with me... I have fun, the other guy have fun. Ive got what i wanted, no need to be greedy, i want ask a single penny from those...
