i think you guys have it mostly half right, half wrong (no offense to anyone). gomiami is right that d2/d3 need to be attractive long-term options for coaches, because of how difficult getting an elite school is. tons of coaches in this game are primarily d2/d3 coaches, or at least, they used to be. that kept d2/d3 active, which is important for new coaches - nobody wants to pay to play vs sims (well, very small % do). it also allowed new coaches to be introduced to experienced coaches which is vitally important for user adoption. at a minimum, having multiple levels that are viable to stay at long term, is clearly better than having only 1. however, the idea that WIS wants all teams full is off to me. from a financial standpoint, it makes sense *if* you assume the # of worlds is fixed, or are really focused on the reward points cost of more worlds (or other administrative costs related to multiple worlds - which should be fairly minimal, the real cost is users). but really, it is far better to have divisions be maybe half full, i don't know the magic number, but coaches who have no shot at the post season ever are not going to stay - that can't be a ton of the coaches. full conferences are really hard to maintain for the same reason. there need to be enough humans in each world for there to be enough competition, for the game to feel full for those who want it - which the game is really pushing up against. but on the other hand, there can't be so many that the average coach is basically only making the NT on a great season - and that is the case in a full d3 or full d1. far better to have double the worlds that are half full, than half the worlds that are totally full. more reward points hit, sure, but far more sustainable over the long run.
on the other hand, shoe is right that having a strong d1 is critical and that having an easier path to d1 is a good idea - especially when you've already made the d3->d1 journey in the past. having to grind through multiple levels you don't want to play, it just makes no sense to me. flip side... saying you don't want users to park in d2/d3 is a narrow view of what this game can mean to people, and its a poor judgement from a business standpoint.
all who said those numbers in tark were good in any sense, no, they are terrible in every sense. tark has traditionally been one of the strongest worlds, its d1 was roughly tied as strongest or better for basically the entire time i was here. a huge part of that is that it was the first new world in the games' history (except for new worlds that came out one right after another in the beginning), and was also the only 2/day for a long time. the # of long time vets i saw still in tark was probably the highest of any world, before i left when the new recruiting came out. those vets are the primary population, except for the whiny idiots who are upset regardless, who were most appalled by the last two recruiting changes (3.0 and the new engine release / d1 recruit gen rework from the last major update). it is also usually long time users who quit when things change, its normal for a big change to push end-stage players over the hump. having more vets was good for tark for a long time, but also if that is mostly who left, it would make sense why tark would take a bigger hit than other worlds.
