I'm not too experienced with SMN or PUP but, I'm pretty sure their pets aren't any where near as sturdy as our pets are.

PUP also has a 20 min recast on there puppet, though they got that dues machina(sp?) thing but I'm pretty sure they come out in a weakened state.

SMNs... well how often do you see a SMN meleeing and doing enough damage to keep up with DDs with their attacks.

From what I see its like:
PUP has more damage output from player. (Though there is the mage puppet i guess.)
SMN has more damage output from the pet.
and as BST i think we kinda fall in the middle with about 50% damage on both us and pets.

Though this is more from a theoretical stand point.

Not posting this just to be a kill joy or anything cause i don't want to start a violent argument or anything.
Simply trying to point out balance issues so we can find a way around it to make the idea more plausible.
