Viri, try not to generalize
I've done most of the quests after I GMed, because I'm a lazy person, and dislike to carry potions and such on me.
I would think the main purpose in 4D would be to fully explore every zone and complete every quest ; otherwise, it would just be like any other mud, grinding to hit maximum level. The tokens and equip are just bonuses
It's true that I idle about in recall these days, but I have a somewhat hectic schedule these days, so I have less time to MUD.
However, I think what the mud needs is to overcome its inertia of having few new players. Players come in, and either stay in the MUD, or leave, due to frustration of completing some quests. We can help yes, but only limited to questing techniques and referring to room descs. As such, we gain very few players. Now..if we had many new players coming on together at the same time, with a greater number of them staying *as well* (at least, for a short period of time), this in turn could make more players stay on in 4D and continue on questing, due to the perceived idea of the majority in the same boat (ie, haven't solved any of the quests).
Iwku, Grish, Knecht are examples of players (in my opinion), who haven't hit GM yet, but still continue on questing, and I believe that none of them solve any quests in the 'new' way.
Oh and..warrior (after the changes), looks like the worst class (for T1-T2s) at least, with lack of any helpful (unique) skills at T1 and T2.
