Paws, for sure!
I know some people get frustrated when others ask for paws in chat, I get it. But honestly, it's worth it to be able to reward someone in a way that doesn't take anything from me but might make their day better. I appreciate when a user helps someone in the forums, doesn't escalate a disagreement in chat, or is trying extra hard in Explore to earn their first Premium upgrade instead of asking for currency (because we all know that Explore grind can be tough!) and I love being able to give people a paw for that!
I just hope it adds a little boost to someone's day. I also just like collecting them myself -- 392 and counting!
