Personally I think Rangers lack the ability to put their pets on “aggressive stance” like in WoW. Where a pet would attack the nearest enemy. I haven’t seen any other posts about it, so if there is one, do please give a link to it.
The main reason I think its needed is having to press attack all the time to get the pet to attack first, is a bit annoying. Having it on an aggressive would help alot when farming/grinding for materials and specially during the Griffonrook Run Jumping Puzzle. :P
