Ok, I went through most of the dev posts ( and a few other ) since Page 5 and the tree picture...
Here are my comments and worries :
From what I left of the post above i have a few questions and comments :
Will it be possible to take enhancements from other trees than the 1 Racial+3 Pre ?
For me, tucking us in trees like that is putting restrictions on the customization possibility instead of opening new opportunities.
Unless you have decided that there's a bunch of things that will be common to all races in the Racial tree.
( Skills, Toughness, Stats, ... )
On the same thing tucking us in trees that way will make it impossible to have a mechanic master at sneaking... unless there's some cross reference with the tree of the Assassin, or you duplicate the sneak bonuses of the assasin tree in the mechanic tree... Or you add a Class Tab that has all the non PrE but Class specificenhancements tucked in.
Follow up on the tucking us in a tree .
Typically : why couldn't I take any extra song as a Warchanter or a Spellsinger ?
Typically : why couldn't I take Dex I and II as a Mechanic instead of Int I and II ?
Typically : why couldn't I take the Sneak attack stuff as a Mechanic ?
Last what of those that doesn't want to follow a PrE path ?
There's some out there that don't want any PrE on their characters.
Now what of the Race/Class enhancement stacking ? ( Typically Fighter Toughness/ Race Toughness )
At first I was really interested with the idea, but since then I've become doubtful.
Time will tell, this is really going to be a make or break change when it goes live.
