Generally Erik is not a bad guy, but he has some personality issue, he desperately needs admiration and recognition. From 450 LS nuke (bireme bomber or how he named it?) and 10000 harpies to all those ridiculous stories about himself in grepo, like how he bought 140 olympics CP in a dead world.
But I tell you what happened.
Erik's style of playing Sinope was time and energy consuming, you could stay updated just thanks to Erik's MM. Time went by, and this madness cherished by many CS and then Merge players went too far. Alliance wasn't built for players, it was designed for Eric to achieve the absolute greatness, as supreme leader and WW landlord.
At the certain point it became clear that Erik is a good motivator, but "specific" leader. If you run a company, own a business in RL, you know that you can't be a manager, accountant, production worker, courier and porter in one face. If you want to run a big succesfull company you need to delegate rights and responsibilities. Moreover as CEO you should see and know all your staff, their strengths and weaknesses, so you're able to make the right choice. You can't simply hire 1000 random people and expect them to be a team.
While Erik was trying hard to be everywhere and live under the beam of the spotlight, focused on cherishing himself, enemies developed enough hatred and motivation to pull together and fight back. When Merge failed to build 7 WW, it became harder to fulfill his promises. So here (right on time!) came summer vacation with family, so all players were like: "oh yeah, it's just a game, and RL is more important (you know, blah-blah), let's wait for Erik to come back and lead us to promised 7 WW."
But in fact when you go to long-term vacation and take time from grepo, after 2-3 weeks you don't really want to get back to daily grepo routine and if your RL is not bad, you become lazy to play grepo again.
Erik did realized, he was losing his "majesty", as enemies took an initiative, The Merge didn't work, as it wasn't a team, but randomly gathered players. So he didn't want to come back. He postponed his comeback several times with new RL smth, as he knew once he's back, he would be under pressure and most likely he would lose WW city. Meanwhile players' dissatisfaction with Erik's RL smth was spreading.
But luckily for him, here came Praehelios' city loss. So Prae became the black sheep for chaotic herd, despite it was confirmed by few players, that Prae did asked to take his WW cities, as he hadn't time to play Sinope. It was understandable as he was busy in RL and preferred to play Abdera. I don't want to defend Prae here, but he's smart and knew Sinope was lost, he just didn't want to admit it openly, as he's polite and prudent. Anyway it had been expected, so could've been prevented.
Let's get back to our "hero".
To right all (mainly his) wrongs Erik had to basically live in grepo for 24/7, but he had a fear. Just imagine what forums would be like, if HM of Fluffs operated Erik and took one or few of his WW cities? It would be the biggest humiliation for Erik in his entire grepo-career (at least he thought so).
So he made his decision, based on what would be the lesser of two evils for his reputation in a short time frame. I would like to stress here, the lesser evil for HIM, but not for the TEAM.
Of course he needed something to put there to smooth a bit the situation and keep the loyal fans believers, so there came "mysterious smth happened in RL". And here we come again: "yeah RL is more important and etc". He shouldn't have left the alliance and destroy 3 WW.
It can't be surely said if "RL smth" was made up, was/is that huge or happened for real, but he surely used it to get rid of the fear of losing WW city, and listening to the laughter of HM (especially) and Fluffs. Just imagine that? Knowing Erik it would be the worst case scenario for him.
Meanwhile because of that action, despite destroying 1000 players' hope and chance to defend their well-deserved 3 WW, he can count on the sympathy and understanding. Moreover, I won't be surprised to see him as a leader in grepo in the future and the same fooled Merge guys will follow him.
Why?
People love to have a faith, and Erik as a good motivator gave it to them, so they simply don't want to believe in smth else. It's easier to believe, than don't.
Don't get me wrong, I can't say he's a bad guy, but a big child who got to be in the center of attention, which he desperately needs to live his happy life.
When spotlights in a theater are switched off, actors who were kings and queens on the scene, become ordinary guys from the subway train.
That grayness is lethal to Erik, so he needs you, he needs guys like the original poster who would admire, respect, remember and love him.
