I rummaged a bit through the files yesterday ( >.> <.< ) and I'm fairly certain that tags / responses exclusivity and similar things can be easily modded if Larian won't make any significant changes to the system.
That said, I dislike current system :| can't really get into RPGs where main char doesn't feel like completely 'mine'. But it always boils down to personal preference and apparently pregen presets are quite popular.
