I do not like the proposal, because it favors only those players who spent most of their time in "skilling" their characters.
In my opinion, there should be a balance in skills between "RP" and "PG" characters. Example 1) a character is regularily IG for one year and roleplays to be a warrior and does training mainly in groups with others. 2) a character who is IG over the same time period, but only focusses on skill
gain. Character 2) should only be SLIGHTLY better than Character 1).
That's why I like my "fast skillgain" proposol so much: only 1 skillcap per day, but reachable in (some) minutes. This gives ALL regularily playing characters a good chance to get decent skills. Don't forget, this should be ROLE PLAYING game, not a SKILL FOCUSSED game. In my opinion, this base concept got lost completely.
I do not like skillgain for money, but would prefer skillgain for role play / quests, alike proposed by Estralis.
