I applaud your decision to drop the Map Updates. I did that myself for quite a while--and then turned them back on. Here's why: You just can't get accurate enough info to do a decent track with IMO. It's too hard to make range estimates outside of 5000 yards so all the work has to be done at the last part of your approach. You wind up doing so much work to get a decent setup that (for me) it puts too much work into the fun. I've got that fine crew taking care of things for me and I consider that to be the trade-off between fun and too much work :hmm:.
If you really want to experience a challenge (if you haven't done this already) turn off external view. Doing that completely changes the game, especially when you're being dc'd.
Again though, I applaud your desire for more realism
