Congratulations on your achievement which I do not wish to undermine. However I feel that such distances should not be possible.
Now that it is possible to jump such distances the meaning of the phrase "long range" has changed. Now long range must mean Colonia. Sothis and such places are now just next door. The Galaxy just got smaller, at least for those have the time and desire to pursue the wizard quests. For those of us that don't.. well I for one feel oppressed by the challenge of keeping up. I can no longer climb into my Asp explorer knowing that it will out jump everyone else, or my cobra which could out run anything. The same will apply to other aspects.
Pre-Wizards, your ship choice and fitting was a strategic choice. You could ensure that you excelled in a particular area that suited your game play. Us time-poor commanders could put some effort into this and would confidently set off knowing our own advantages over others. All that is gone now.
I have a certain sympathy with the argument that you don't have to partake if you don't wish and I am currently playing in Solo because NPC's currently don't have engineered mods but I'm sure that will change. Also it dos not take a huge amount of imagination to see how the game design will alter to reflect these magic upgrades. The new short range missions (all non Colonia systems) will become less well paid. The harder missions will be designed with a modded ship in mind.
And when will it stop. Are the wizards suddenly going to pack up their magic chests or are they going to keep making up new spells until it is possible to jump across the whole galaxy in one jump? Destroy a station with one shot. Cruise along 10,000 m/s! "Don't be ridiculous" you say to me. "You're just being silly", "That'll never happen".
Well if I came in here last year and said "I reckon we will be able to jump to Sothis in one jump from the bubble" you'd have said the same things.
