This is an important point and something that I think goes overlooked. Lots of players seem to believe that they should be richly rewarded for grinding arbitrarily high in any skill. In reality, skills where you CAN be useful or competitive or self sufficient without needing world-class levels in them are important for the game. Not only for solitary players and pvpers that just want to "check off" AH from their grind list and move to other things, but for players that DO want to specialize in them, participating in economy and/or their community, without needing to grind endlessly. When I played as a teenager, I almost exclusively did strongwall and enchanted grass casts, as those were 2 things that required no traditional Wurm grinding but let me be useful and make some money. Not all skills have to be worthwhile grinds to 90.
