second is that the elastic of training is being expanded to include (some? all?) secondaries (ie. training OD will be harder if all the big man skills are at atrocious).
I think that elastic effect will not slow down if there are low unrelated skills. It just train them weakly too (if there is elastic ON), I suppose.
Im also looking forward to see these changes. However I dont expect any further explanations, because there arent much about cross-training itself in the rules etc.
So we have to wait now 3 months.
