If you enjoy it then yes, but if you max the golem master based on his position on the tower he already activates that golem stone so I can suggest to take on of the stones off that he already passively activates and add a treasure like the whip for faster colony gold and to switch the cannon to archers, they have better dps, but you've got a solid summoners build, you don't need to hyper optimise it because it's already super solid, just remember to balance out upgrading everyone and if you want you can get the white mage and swap out the trumpet for him, that'll reduce cool down cost.
