A final note: don't trust NT trainers for understanding the game, they are usually good at communications (which won them the election) rather than knowing more about the game mechanics than everybody else. I'm one of them. :-)
And while we are on the subject there are situations when the slowdown related to a runaway skill just can't be avoided and you just have to live with it. I am not about to stop training OD for example just because the other skills are lagging.
Just by how much would you say it slows down? I plan on tacking OD to about 17-18 while the HN and DR will stay at around 12-13. Will I have significant problems doing that? I do plan on doing quite a bit of one position training were OD is concerned.
Will training it indirectly still produce a diminishing return?
