I started playing EVE in 2013 just in time to see the tail-end of the Golden Era of sov-warfare. I got to participate in the Fountain War as a wide-eyed newbro flying a Slasher and I got to participate in the Halloween War flying real ships, just barely missing out on the Slowcat fleets as my carrier pilot finished training a couple weeks after B-R. During that era the kind of tidi you watched or experienced in 9-4 wasn't a failing on CCP's part, it was simply an accepted part of the game. In the Halloween War especially it was a bi-weekly occurence for months on end. I'm not saying no one complained or got annoyed about it, but instead of a problem to be solved it was a reality to be accepted. I think the relative peace of the last couple years has left a generation of EVE players without a fire to be baptised in and the outcry from last night's fight is simply the understandable reaction.
I've long been of the opinion that large blob groups suck. Not that they are bad winning at fights as that is objectively not true, but simply because almost everything they do is geared towards winning these ultra large fights that have absolutely zero appeal to me as a line member. I'm sure that the morning-after feelings of "what the actual fuck am I doing with my life" have many of you feeling the same way.
As long as there have been alliances there has been soul crushing server lag. TIDI itself when it was introduced was seen as an ingenious solution to dealing with permanent black screens where players would jump a gate and spend 30 minutes at a black screen, only to wake up in a station as they'd died uncloaked on the other side of the gate. It's a good compromise for a hard problem.
The point is this isn't going away. People have spent years waiting, quit, got married, had families and came back on a limited basis in the time it's taken for us to get here. If you don't enjoy it you need to seriously re-evaulate your playstyle. How about joining a smaller group? Maybe you'll decide you're happy and that's okay, maybe the "I was there" factor was enough for you. But for me it wasn't and I hope for many this will be the catalyst helps them make the same decision.
