I respect anyone with the knowledge to design tools for any game I mod. From total war, Rotk, Dragon age etc. That being said. Some of the best mods I ever used/created came from people with no knowledge of tool creation but a great knowledge of the tool. Some people can use the tools you make better than you. Saying a lack of that particular skillset doesn't make you a good/great modder is like saying using a game engine you didn't code makes you a crap game designer or a mechanic that didn't design the wrench is a bad mechanic. Stay humble. Everyone has different skillsets. Everyone contributes differently.
