2.2's single biggest feature for me was the Ancient Ruins sites ( pew-pew bores me ) - the code for this wasn't even turned on at release time! - we had to wait for 2.2.03 to turn it on - then it was horribly bugged - from beta testing at the ruins sites I'd say 'most' of the bugs are fixed ( but FDev never really admitted to most of them and in the release notes we just have 'Multiple fixes to address problems with an Ancient Site' - hopefully this is bug in the release notes since we found 100+ Ancient sites! ).
Well yes, I didn't even mention that.
I wanted "The Guardians" story and gameplay to be awesome. It utterly failed by missing 2.2.01 launch, 2.2.02 update and 2.2.03 was a total . I did the missions, I joined in with the community and to be frank, the whole experience was utterly ruined by godawful buggy/incomplete/poorly-implemented execution from FD. Perhaps in another six months we can have the gameplay that was promised for the ancient ruins and guardians missions with 2.2's bugs ironed out. Like most people, I quit in disgust after hitting all the bugs/instance-drops as everyone else and only a miniscule minority of full-time, hardcore spreadsheet-scripting players persisted with trying to find the "gameplay".
