I'm all for a clear. I'm one of those who has never made it past RL 10, because of the gods and supergods constantly getting in my way (AFKing in decent zones, mugging, mimic killing, killing in general, shoving offmap... The list is endless).
Anti-AFK stuff would be necessary. Something which requires a random code to be said every few minutes, made in such a way that an AFK script couldn't get around it. Anti-AFK stuff could also include faster, more dangerous fights with bots (At level one, you can kill the weakest enemy in 4-5 hits, but it kills you in 1-3), which perhaps could have a lunging/hopping ability to prevent getting stuck in stupid places *points at Mino Lair*
A generic class would probably work pretty well. SP could be removed, and skills would be trained entirely by using them (much faster training than what it currently is, though). A character's class and skill increase rate would be defined by how often that general type of skill is used. Attributes could be used instead of that, too, would affect the speed at which the player trains certain skills (STR+DEX=Slash,STR=Bludge,DEX=Pierce, etc.), and would be determined by what kinds of skills the player uses. Endurance or strength would be trained by running or fighting, for instance, wheras Inteligence and Wisdom would be trained with magic skills and reading (Perhaps add a library?). Attributes, skill levels, and player level could work together for weapon, armor, and spell restrioctions.
Remorting could probably be removed, and be replaced with a much slower leveling system, up to level 999, at which point the char could restart, but keep all of their stuff. Many more zones and emeies would have to be added, though, for this to work.
Items should be smithable for free, rather than having to pay a smith to make them for you. A master blacksmith could, however, be paid to make some of the more difficult to make items. Mined items, rare items, and armor could probably use the same system as SINISTER's Belt system, and allow more weapons and accessories to be added (200 itemData limit on Tribes :< ). The resale rate should probably be MUCH higher than 8% of the original price, too, since making money is hard as hell for newbies with no Haggling skill.
Any comments on the above ideas would be appreciated. Please keep it somewhat polite, though, since I'm only trying to give a few suggestions for how I think a TRPG server would work the best.
