The current selection of guildmarks/traits are mostly abilities. If we have 11 traits to choose from i think that might add more depth than just handing out abilities every other level.

It would be great if we couldnt choose all the traits to use but need to select a few; add diversity/customisation for each class.

The current state of the classes it would seem that only ONE trait is relatively useful per class. IE: fleet of foot from lancer or out of sight from archer.
