I agree that grouping in WoW isn"t nearly as rewarding as it should be, especially in the xp department. Honestly, grouping should be the supreme form of xp imo, with soloing a definite second place. Reason? It takes more coordination and effort and in many cases "time" to group up and take on group challenges. I can"t remember which random mmo it was that had a quickly scaling xp curve, but by the time you filled the group, the bonus xp per mob for being grouped completely made up for the fact you were getting it split, then you add in that the many more mobs were killed in a smaller time frame, you basically grouped to do xp faster as opposed to it simply being required. The xp bonus in wow is negligable, when it should start appearing at a reasonably noticeable amount as soon as two soloers form one party. 25% xp increase or something. When you get to max group size (whatever size that may be) you end up with each mob being killed giving the group 125%-150% per mob that the single player would be receiving killing the same number of mobs.
There"s absolutely nothing wrong with solo play in the slightest, but it shouldn"t be the fastest way to progress. Come on Curt, cater to the hardcore with preset cliques in their desire to hit the endgame hasta pronto style. Just sayin!
On the topic of twinks, I don"t do it on the average. WoW being the slight exception because of certain characters I played being entirely too pigeonholed from what I was fooled into believing they were at the early game once I hit max level. Shaman and paladin, for example. In EQ my highest alt after 3 years was 35, and he was legendarily twinked. Nothing like having a newb dwarf paladin with soulfire and full Deepwater sans BP doin the Fungi Tunic dance on Orcs at level 6. Yay for multiquesting. My SK had 350ish days played on him compared to my paladin"s 1.
That said, I think it should be relatively impossible to epically twink a "new" player. A new character on an experienced player"s account? Twink away, I have no issues with that. Level 70 gear on a level 9 character is peachy. But each player should go through the same experience as everyone else as much as possible. Granted, this is assuming that the game doesn"t have a gameplay plateau like WoW did, where the 1-59 game was night and day with the level 60 game. Awesomesauce shaman dps/tank/healing machine? No, you"re a healer with light dps, better be spec"d for it! Awesome ret paladin who rained hammery justice on the skulls of undead? No, you"re a healer with negative dps, better spec for it! In the class design phase, classes should perform the same way at level 20 that they do at max level. 20 being some random arbitrary window where the majority of class abilities are either known or at least hinted at. Don"t pull the ridiculous Refresh silliness that FFXI did with Red Mages and how your job went from great utility healer/dps/debuffer to refresh bitch with one level.
As to actual implementation of the "no new player twinking" concept, simply have accounts flagged as they progress, with each progressive level reached opening up dropable gear of that level being able to be worn by characters on that account. Yes, some new people will start characters on existing accounts of friends and what not, but it"ll curb the majority of it.
To be honest, the concept of "twinks" is largely dependant on the type of gameworld, the itemization parameters, leveling speed/skillgain accrual speed, endgame goals, travel and a whole shitload of other factors. If your game is an exact wow clone, then twinking in and of itself isn"t that major of an issue, though BG twinking shouldn"t work. Everything is easily accessable, leveling speed is as minimal as it gets without simply handing you max level on a silver platter, even for new characters. There is little challenge in solo quests of the same level unless you are horribly undergeared and too poor to afford skill upgrades and are spec"d wrong as well as being mildly retarded or just plain terrible at video games in general. Travel is minimal (minus flying from anywhere to tanaris. Fuck) and gear upgrades are almost always level controlled anyway. Other types of games will have different mileage depending on how easily attainable gear is, how far travel is and the aforementioned slew of factors. Plainly put, need to know more about your game Curt!
