I dont know what group youve been playing with, but my personal experience is that some groups do or at least did use printscreen to capture the coords on the map and before the map on the F11 to post in TS for the revenge/delayed fleets to come, before the teleport to port option was implemented.
For these fights, the coords were the determing factor to wether the fleet was standing on top of the battle exit and was able to re-tag the other ship(s). when people were using relative coords it was far less successful, had to deploy wider, not saying it was impossible, but it was less of a guaranteed 2nd engagement.
Now that we will be forced back in open world, im sure that a chance, even slim, for people to avoid a poinpoint revenge fleet (not against the revenge fleet, but that accuracy of it) will be welcome more than the GPS.
Might as well keep the coords data in the f11 reports but hide it from the players so that it cant be abused.
People will learn to play without silver spoons, I have faith in the average human to be able to adapt and use the tool in game for navigation and Im convinced that if will make for a richer experience to travel without aa pinpoint accurate GPS.
