Current: pets get a very cool perk at 55 with no further listed progression bonuses
Suggestion: perks or bonuses every 5 levels thereafter (60,65,etc) for fun, difficult to attain pet utilities, feats, or bonuses.
potential bonus ideas:
-- another perk point every 5 levels
--lvl 60 pet gear that's perma-lockable to the pet (stays equipped in/out of kennel)
--lvl 65 pet incrementally better pet gear?
--lvl 70 permanent primal transformation? Or special evolution to primal but back to lvl 1?
Balance issue: recommend making pets untradeable after 55 or after 55 perk(s) accepted.
