The whole fucking server hated CT. Whatever you thought of FoH, CoE, or CD, you could take them at their word and deal with them. As someone who lead a B tier guild (too casual, never made it above 30 people and PoP ultimately made me hang it up along with getting engaged), I always felt I would get a fair shake out of nearly any A team guild on the sever.... except Complete Tools. Even the ones we hated and hated us would keep to the code. FYI I gave Xerx the haste sword for the mecha cazic incident. It was mostly due to having CT try to steamroll multiple friends over the clicker and having them lagging the fuck out of ToV wiping to Guardian Wurms screwing our Dozer runs.
A Tier Guilds on Veeshan FoH > CD > CoE > Valhalla > Legion > Ixtlan > Tess Era CT (when they were respectable). Anyone else on that list is even gimpier than my guild was and at least we got halfway through PoP with 30 before CoE absorbed our core people (my idea, I was about to retire). I say this without bias, because a lot of people in those guilds and I had a mutual despising of one another, but at least word given was word kept (unlike CT).
Casual Guilds, I don't want to give any order, because I would show my bias, but there were many good ones that fed talent into the top dogs, some of whom I can no longer recall, but my faves were: Azure Guard (solid dudes), Obsidian Guard, Corps, and Outriders of Karana. Best Asian guild ever was Ted Club.
