Shouts, Signets and Pets should be redesigned to provide group utility which would be easy to do.
I. Signets. The UNTRAITED elements of signets could pulse from the ranger up to 5 using group mates as first priority.
Additional Idea: Merge Spotter with Signet Mastery.
II. Shouts shouldn’t require 30 in a trait line to provide a group benefit. Move to 20? That would allow you to have Nature’s Voice and movable spirits.
Additional Idea: Traited shouts could also be blast finishers. (Blasting your voice).
III. Pets should apply stat bonuses by class of pet to your group or 5 targets closest to pet. Again, it would be a pulsing stat bonus so long as the pet was alive.
Additional Idea: Make all basic attacks AE but with a short radius. (Get more attacks, more AE and they should hit more folks being AE).
