(Just FYI Poki, your posts have become an interesting fixation for me. There is a deep Type C lesson brewing, but I cant tease it out just yet. I can just feel it, but cant sort out the connections.)
Its odd as due to Ne, I always start off understanding the entps, but they loose me in the Ti details-which are still exceptionally abstract, Ne not Se. But they love systems and high level concepts. But it sounds like you are saying you see them get stuck in details and you love systems and high level concepts. Yet you are very much an ISTP, especially based on that last line about being the secret weapon. ISTPs are the BEST secret weapons.
Could your "high level" mean an SeNi version which would see NeTi is being crammed full of useless details and missing the point?
Much like INTJs, ISTPs can move mountains but the mountains have to have an immediate tangible reason to be moved?
idea generation based on past experience-NeSi would do this. But it sounds like you use SeNi to do it as well, but highly tuned upon the objective end goal.
