I think that the main problem of RA is that he is not smart enough to create a map that has strategic/tactic valors. His maps are good looking, but nothing special when it comes to gameplay. He is a decent painter but not an architect.
That is why he needs to STEAL designs from other players...
it is hard to concede good values to a person you dislike. Your statement only shows your lack for an objective analysis. The fact that Ra won the 2v2 ladder pretty much refutes your attestation. He also made both kinds of maps - those, that focus on art and others that are meant to be used for competitive games (these maps are very well made and good looking,too).
I got to know Ra a little bit better in the last months, where we started a map project together. He is a smart guy with little interest for social bargains, which doesnt mean he is stupid or unreasonable. I guess he dont care much for a proper citation or giving credits within warlight. He makes the maps for fun and to improve the game. Some of the overall best maps are made by him, this is at least something you could appreciate.
Im sure he would give Nic credits if you ask him personally (not in the forum - without the lynch mob in the background) and beyond that Im sure he would even apologize. I havent recognized malice within his behaviour, rather an immature conception of social standards.
