Attacking the developers are never okay and should never be accepted. The developers are the one's that reach out to us. If we are mean to them, then they are going to do as many other game developer studios do and just leave everything to the community managers or not have anyone at all.
It's really nice that Maxis has these simgurus and it would be really sad if they would all go away because people can't behave. I hope that they have some people that can help them with this. I think there are tools so people that say very rude things does not show up at all, and shadow-blocking works for individuals as well.
I am not so thrilled with this pack, I was not so thrilled with the knitting pack in the beginning as well but I always thanked the developers for the updates anyway because they are the one's that reach out to us. And I think that is important.
I remember contacting origin support about refunding a game that I did not like and he commented how refreshing it was to talk with a person who just simply said why they were not happy with a product but in a completely reasonable and nice manner.
