While they're at it, why don't they give the Spire the health of a Galleon? That'd make it a much more viable option 
Tar is effective enough as it is.
While I don't appreciate the sarcasm, I understand your point. And to be honest, I always thought the Spire could use a small boost to the health (just not as much as a Galleon, per your exaggeration, as during the 3x hull event the Spire was a beast).
And "tar is effective enough as it is" is your personal opinion. I respect it and I won't try to change it, but I don't have to agree.
Just out of curiosity, Sunderland, what piloting tools do you use?
