I dispute not being able to effectively defend against spinners, in my 5 years of building I’ve never taken substantial damage from a spinner, even having fought some of the most damaging ones in each class (barring heavyweights).

Defending against spinners really isn’t as difficult as a lot of people seem to make out. That said, I wouldn’t mind seeing more clever ways of entanglement, but nets etc would be painfully boring and quite unsporting to be honest.
