Well, this time i will start by telling you which my hypothesis is and then i will try to show it is right, so you can after that decide wheter i am right or not. I just think one turners (ot, from now on) are just a sub-product of game development.

What i mean with that sentence is that i think game developers did not want ot to exist in the game, but they just appeared as a logical result of skaven, for instance, being the fastest race in the game. I just think ot unbalance the game, much more when the teams owning them have more than 11 players so they can avoid setting them on the pitch when in defence. I know its you, as the opponent, the one having to assure that the pesky ot is on the field just by putting some other players out. Thats right, and it does not go against the sentence that says they unbalance the game: unbalancing something is not the same as destroying it. If ot were impossible to counteract, then they would destroy the game, but they just unbalance them.

Going on with what i said, skaven, for instance, were designed to be fast. So gutter runners, the best of the best in skaven speed, had to be faster than the rest of the team. And the rest of the team (linerats) had to be faster than the average (human linemen). So the minimun movement for linerats was 7. If gutters got 8 movement, then, they would just be as fast as fastest human, catchers, so it leaves us with only the 9 movement option. And as general rules allow players to get up to +2 in mov, agi or str, you then have the ot chance out there (as half pitch is 12 squares long, so you have to run 13 to make a one turn td).

Assuming we wanted to avoid ot to exist, what can we do? (lets now put the bb designer hat on)

1. We can reduce every player movement in 1. No way. Then treemen would get ony 1 movement point, mummies would have to roll to stand up and bobs and every linedwarf would get 3 movement points, which is too low for the team.
   
2. We can make the pitch one sqare longer (on each half of it). Hum... That means 14 squares to score, so dwarves and orcs, for instance, would have to gfi twice just to score in 2 turns. In general, it would make the 2 turns typical score too dificult for non elf races
   
3. We can make special rules so ot cant appear. That would mean not allowing any player to get 13 movement, not even with GFI, or something like that. Then gutter runners or woody catchers would not be able to develop normally, as following the general rules
   

So, as not having any logicl thing to avoid ot to appear, and being ot not so often developed, lets leave them the way they are, the community would just take care of them when they get on the floor ;) See you all, guys!
