How difficult would it be to adjust the runspeed?

At the moment we have some problems with the servers not being able to handle the high runspeed of the NC characters.
The "Clipping"-Problem is getting adressed already, but maybe we could adjust some other things too.

Every standard cookie cutter build relies on speed. Agility > 150, ATL >= 100 and there you go. Result is clipping, characters "flying" above the ground and netcode getting completely fcuked up.
You do not need any movement (dodging, changing direction and so on), everybody with low HP is just running away.

Maybe you could decrease the runspeed to a good amount, so that there is something like a "harder" softcapp?

But of course I also see some problems.
- Melee Tanks are not viable at all in OP Fights at the moment (they are perfectly viable in 1on1 situations though), if you adjust the speed melees become even crappier.
- Less points having to be spent on Agility means more points spent on R-C or P-C? On the other hand less points spent in ATL means more resist?

Getting the formular for calculating the runspeed would help a lot btw.
