Switch Traits and Abilities progression (3/6/9–4/7/10)
It seems a shame not to get to use those Level 10 Abilities more than a few times, in just two quests (discounting replay as outside a story arc). Why not gain access to new Class-specific Abilities at 3/6/9, and Traits at 4/7/10? Generic Abilities require higher Traits, and I might be unhappy not to get Dash until Level 4, if I start with only 5 Agility; but the Level 4/7/10 Abilities don't require (I think) a minimum Trait value, only the appropriate Class and Level. Since they tend to add some really cool stuff (e.g. multiple attacks, utility-like functions), the Class-specific Abilities might be consolation enough.
Another possibility (not officially proposed here, since I saw it elsewhere) would be to allow a point to spend on Traits at Char-creation; this would obviate any worries about having enough for generic Abilities before Level 4.
