I think erjoh is making great points about the controversy of ToC issues; not invalidating or validating the choice to rollback though.
I’ll add on to erjoh’s assessment of why those crying foul at the rollback is an issue, mostly, for PVP.
If you happen to be on a server where there is the delight of an actual war this especially matters:
Every choice counts. Every slam of a pickaxe, queue of armor, scout of a base, note of words spoken. You have to organize yourself well and make it so your time counts. Much of it can influence the outcome of battles. Time is money, friends.
So, based on status quo, most believed a rollback wouldn’t happen and that’s even if you knew about current affairs.
As a result, the usual schedule went on. Meaning raids. If you happened to scout the hidden location of an enemy and hit it during those 2 days it not only means all your preparations were for naught as they move and you have to re-scout again.
Anyone who does thorough scouting knows how time intensive it is.
Triumphs of taking down a server alpha were erased. And the Alpha could take what they learned and use it against their opponents.
Some of these battles may have been a 48 hour ride, but perhaps weeks if not months in the making for some (if you’re lucky, again, to be on a server like that).
I’m not even talking about the discovery of exploiters which now could move either… That has its own caveats and impacts.
All this to say that as a PVPer who engages in this play mode and understands the intricacies of time and choice, I get WHY people are upset.
However, it still pales in comparison to what others have lost in much, much, much greater numbers.
I agree with the rollback. It was unfortunately the least impactful way to correct the error.
It still sucks.
