I think EOD is a good expansion, with strengths and weaknesses.
For the meta in the Jade Sea and the final battle,
even with a very well organized group,
last attempt failed at 6%, you can't just blame the
lack of knowledge of the mechanics. Again and again I had it
now in the final fight that e.g. the eating phase comes twice in
a row and my can not do any damage or the phase with the tail
comes a few seconds apart. In addition, with a minimum of 2
hours of effort, the loot is very disappointing,
you get more out of other metas.
For me personally,
I will no longer play the meta in the Jade Sea after I have
successfully managed it at some point.
