I am glad you found us!
We are a casual guild and learned that going hard-core towards any one activity causes burnout haha. We dabble in a bit of everything, but don't hard core push or guilt trip folks into participating.
As a guild we coordinate activities on our discord. Each week we schedule 2-3 raids as 'sign ups'. This gives folks a chance to get in on a raid they can 'count on' going off. We usually include an activity that pertains to conquest (Could be a heroic run, FP, World Boss, Operation or PvP). That give folks a chance to learn about conquest and easily get the extra rewards that come with hitting their target.
Additionally, we have lots of 'spontaneous' groups that form up randomly. Generally speaking, those are all over the board, depending on how many folks are online and interested. We organize those in a channel in discord called Looking for Group. Paxians as well as our friends and Allies have access to it. Anytime someone is in the mood to do something they post in guild chat, and follow up in the channel with a note as well. WB's, MFPs, and operations are common.
HM ops we currently don't schedule, only because that was the last activity that burned folks out. That caused some folks to 'take a break' from the game. However, in the last month or so, several of our members have voiced their interest in starting them back up again. It is worth mentioning though, that we have had a surge in new members who are new/returning to the game, who may not yet be ready for HM ops.
Additionally, I don't know that we have ever tried to organize HM chapter runs. My understanding was that the reward to time ratio wasn't favorable to most players.
One of the things I love about our guild, is that it is very much, 'If You build it, they will come'. One of our members did World Boss Wednesdays for a season to try for the achievement speeder. Another wanted the Master FP achievement and regularly organized runs for folks to get it. I myself got folks together to complete the Shroud quest that had been sitting in my log for years. Most of the folks in our guild love exploring the game, and just need a target to hit.
I encourage you to at least check out our discord. Message us when you are in there, and we can assign you a recruit role and get a ginvte in game. You can then review the history of our channels to see the type of activities we do and how often. You can also see some of our general silliness that we have as well.
