The Madness is not that crazy or is it ?
For as long as i can remember (once i figured out how to properly ? play ) i have kept my pets most times on Aggressive , i still have full control with the stay and follow and still use the attack button at times.
My reasoning is mainly that the pet was a wild beast and deserves a little choice in what it attacks , but saying that if not for my pet attacking mobs i would not have bothered with i would not have seen as many greens and blue drops as i do , and i have lost count of the trash grey mobs that drop me a nice profitable blue.
Many i guess will say they have tried it but could not control the pet or it got them killed , i have never died because my pets were set on aggressive , i use the controls as we all should and still select targets even if my pet wants to attack other mobs , no biggie there in control.
I am not saying that i would use it in any group unless it was friends and they were ready and able to control any outcome from my pets pulling aggro or disrupting game play , but used in normal questing it can be a fun tool to use even if any journey will take at least twice as long.
I can agree that sometimes it just is not worth having my pet on aggressive like in ratchet with pvp players about , so in towns i almost always (if remembered ) switch it to defensive , but i enjoy the disruption my pets have on my questing ( and the extra gold they bring )
Many will disagree with having pets on aggressive but hey its there why not use it at times , as an example my leatherworker yesterday was doing a lowish quest with fast spawning skinable mobs all i did was stand in the middle and select the pets target and fire away , far easier and faster than select a target send pet then fire as i was having real fun trying to keep up with my pet , final result was quite a few stacks of leather and some nice greens in far less time than having to keep selecting a target and waiting for my pet to get to the mob.
Also i tend to think the pet is getting some fun out of it as if you have ever tried my way you will know the pets seems to sometimes get into a killing frenzy ( thats the only way i can describe it ) as it will often travel outside my shooting range to attack a mob then run after any within sight sometimes swapping to a nearby target , i do have to keep my eye on the pets health but not that hard to do , and the amount of times my pets spot a mob hiding when i am not doing the tracking for that type of mob is very useful as well.
I expect many will disagree with my playstyle but i have done it at all levels for the past year from 10 to 70 and never get any real problems as i will switch back to defensive if needed , which so far has only been when PvP players might be about .
Plus points as i said already more drops also most times more exp gained per hour .
I can see only one real fault with it and that is every trip takes a lot longer .
i was going to say a lot more but i expect a few will say i am crazy anyway and it is not the right thing to do , but we all play in different ways and for questing it is my way.
