As an avid RN player, I would indeed be totally gutted if this had happened to me and my account, especially so close to the EG. However from what I've read, they can't roll back the server, they can't just 'implant' the players back in the game with everything they had, there's little they can do other than ensure it doesn't happen again and give the players compensation.
The only point I'd make that does sound unfair is that RN haven't reimbursed the players money they'd spent on the round, that doesn't sound correct. If for instance they spent money that unlocked the primus engine, that was on the knowledge they'd get to be using it *that* round and the gold in those circumstances.
I think also that by not doing this will make the players effected even more angry as kind of forces them to play again if want to make use of the compensation, however if you gave them the gold, career stuff and their money back they might be more inclined to continue and see that it just one of those awful things that can happen with games from time to time. My 2 pence as impartial thread reader.
