Titan attacks lesseningnin points

Hey just asking, I’ve noticed in past few days that my titan attacks seem to be getting fewer and fewer point. Like just now against the goblin king, I only scored barely 9000 points but my attack team (one that I use JUST for titan attacks since healing doesnt really do any good and just wastes time and a spot that I can put a warrior in) is nearly 4000. And I’ve recently been scoring in the 20000 to 38000 range. What’s up? Why is it going down? I recently added harpoon as I weapon and use the bear banner to increase my attacks. Any thoughts? Help help help.
