I don't think there's necessarily anything "wrong" with having a trait choice that provides a significant boost earlier game but less impact later game. Wealthy for example is like that.... and I think it works ok.
Wealthy could be setup in several ways:
+500 starting goldar (like now), early game bonus
+5 gildar / turn... bonus that last all game
+1 gildar/level per turn... scales into the late game
Note those values are probably way out of balance, it just illustrates the point.
Personally I think it's interesting to have a mix of choices, some that impact more early game vs. some that scale better.
So those Sovereign talents missed the point of a level-up system:
Hardy: +1 HP/Level
Brillant: +2 SpellMastery/Level
Discipline: +1 Accuracy/Level, +1 SpellResistance/Level
But yet Might is +3 Attack right? (i'm at work can't check). So there is a mix, which is fine.
The resource providing ones don't scale with the sov:
Wealth +500 starting gildar.
Attainment +2 Mana/turn.
I guess I was looking at the "Famous" trait as being similar to Attunement.... i.e. a nice early game boost that becomes less relevant late game. My specific case.... one of the Sov's in the next D&W version is supposed to be a powerful warrior/leader that attracts followers.... hence I was thinking of a +fame trait. Maybe +1/turn.
