It still don't hold me back as a player to play without using tools, however what it can hold me back from doing is coordinating well with 21-24 other kingdom fellors, that is the whole point of why you use the tools and have nothing to do with personal performance so your comparison is of the mark, it is only those who become so dependent of the tools they can't perform without them that would hurt their own performance by discarding the use of tools in their playing style, but perhaps they would learn to play without tools to in the long run if they did that.
Fortunally for me I play in a 3 man kingdom, so tools are not needed at all, and the ingame chat is sufficient for communication. That is also why my offer to Moon of Earth still stands if he is interested in embarasing individual gameplay he can pm me anytime, because there is no better place for that than in the shell kingdom. I recently made it to arround t200 for land on the server and 2nd for Dryad all that while playing using pen and paper and restricting myself to not exploring at all.
