Now for me, I would say if you're a 'core' person and not enjoying yourself or not getting what you want/need then the answer is obvious. Take your main and go RAID with a guild made for it, leave your alts in the guild and be with the people you've become close with when your raid schedule allows.
Hmm?
What Rox stated here, is thruthfully the point. For everyone themselves you have to make up your mind. There are a lot of raiding guilds having problems to find adequate and good players to progress in a raiding environment. Don't underestimate it though, they will apply rules and you will obey or be kicked out after your 'trial' period is over.
For what raiding regards you will look like this :
- at least have 2-3 days a week time to attend raiding (and that's even very low) mostly the hours of raiding are 20:00 - 00:00 (the more hardcore, the longer and frequently you are obliged to attend)
- follow orders without asking questions nor give pointers, just stfu and do as your told is the bottom line
- loot distribution will be stricked and if you're lucky, they have a fair policy, but most don't
- if you don't raid, you'll be grinding your but off to pay up for repairs, pots and preperation, and no, daily quests won't make up the expenses..
For my own experience the last straws of my raiding days was that it felt like 'work', and i do have RL work already, so i won't let any game give me more work then i would have in RL
All by all, every guild has a 'crisis', and this seems the first real 'crisis' SoG is going in at the moment.
However this guild is mature enough to work things out, the most important question is : are you happy and having a good time when you play? If the answer to this is 'no', then you need to find for yourself out if there is a solution to make your playtime more enjoyable, and if not maybe it's time to give the game a break.
