I've said it a few times on these boards, but GoD was totally fucked. We were 3rd worldwide to kill Rathe (that was a massive cockblock). Other roadblocks were due to blown triggers like Coirnav and the RZ event. It took time waiting for trigger respawns to learn the overall encounters. But yea, Rathe literally took a patch to fix. It relied heavily on RNG with one of the Councilmen abilities. I think Afterlife managed to down it by sheer luck once. Then it was patched to tune down the RNG ability and it fell right after. Afterlife, Township Rebellion, then us Darkwind.
GoD and the following xpac OoW were supposed to be 1 single xpac, including the level increase to 70. Due to time constraints and wanting to rush something out the door, SoE decided to split the xpac into two. You ended up with GoD with all raid content tuned for level 70 + their respective AA abilities. They level increase didn't come until OoW, so at GoD release everyone was stuck at 65. It was a total shit show. I have screenshots of a level 1 GM Dev in our raids on live server giving us GM summons / GM Reses while taking tuning notes as we died horribly. This was all on live server release, not beta! That was the crux of what was wrong with GoD. People at the bleeding edge quit in droves because they didn't want to waste their time with broken untuned content.
I know things were fixed much later and some actually enjoy the xpac. Those people didn't deal with the months of getting it into working content. I too quit the game for EQ2 beta at this time.
