Only very indirectly and in the most minor way. As I understand it the changes are -1 for each 25% losses (only really applies to superior and elite as average would have autobroken) and cant rally from rout if on 50% or more losses. In effect if a superior unit suffers another defeat after already been reduced to 50% strength it is slightly more likely to fail a CT.But FoG is reducing the effects of quality so another nice bit of the rules going.
Frankly these effects are so minor and, in a sense, overlapping (what chance would you have had to rally with at least a -5 on the test anyway) that their impact will be subtle to the point of non-existence. Played a 6 round V1 comp on the weekend and dont think a situation arose where either of these chages would have affected anything for either side in any of my games.
Superior will still be the default choice for pretty much all non-skirmishers when available. The only hope balance will be restored on the quality front is the hinted at future points changes. Personally I like the fact that superior troops really are good in FOG so I'm glad they didn't introduce changes that would have had much of an effect here.
The cost in points, however, should reflect the benefit and at the moment it does not. Of course if they actually do introduce a points system where cost more accurately reflects the importance of quality (it can be done, FOG R does a better job for instance) we will no doubt be submitted to a great deal of whining from the players whose superior packed armies just got a bit smaller.
