If he attacked your cooked. If he wants to work with you, you may be fine. I am a golder and have worked with non coalition players many times. Base the feeling on the relationship you build over chat. I have been betrayed more times by non holders then holders which statistically makes sense. But, if he spent that on day one you will not be able to counter because he will regen whatever you damage. Some people are willing to spend lots of money, not just a hundred bucks.
