Spine customer support sucks! as paid software, they didn't reply to the question from clients often, when you are running your project but can't use Spine, you can't get help from them, it sucks!!
Spine launcher sucks! I know to be a software company, you are worry people use your software by illegal, we understand and we pay, but if you can't 100 percent make sure your luncher can running well with your stupid some license check, don't do it, I can't run spine for 2 days and I can't get any response from this company yet, it is an unbelievable shitty launcher I have never met!
Spine shader sucks! if you use a normal map, the alpha area problem will force you to give up, so if you want to make an awesome character with a normal map, the spine will disappoint you very much!!
awful third party plugin support, Spine never wants to try to support any unity third-party package. like Playmaker or anything, although some third-party plugin try to support Spine, but the result is not good, because Spine runtime update often.
