Gevlon had a post up about gear and effort where he states that "hunting for best-in slots, grinding an ilvl 213 to replace an ilvl 200 epic is pointless." He is immediately taken to task for this attitude in the comments.
However, I'm much more sympathetic to Gevlon's view. We all have our limits, the things we are not willing to do.
For example, here's a list of things I'm not willing to do:
- Switch professions. I'm Enchanting/Mining, and I really have no idea why. But I'm not willing to switch and power-level professions to whatever the flavor of the month currently is.*
- Raid more than 3 days a week.
- Take time off work.
- Give someone else my account information so they could play my characters if I am not there.
Everyone settles for "good enough", it's just that our definitions of "good enough" vary. One of the important factors when looking for a guild is find a guild with a similar definition of "good enough". If one person's definition is much lower than the rest of the guild, or much higher, it will cause resentment, and eventually drama and unhappiness.
If you food+flask every fight, and other people don't, it will grate. If everyone uses food+flask, but you're unhappy about spending the time to get consumables, it will grate on you as well. In both cases, you would probably better off in separate guilds (or at least, in separate raids).
Again, it's about shared expectations. Groups work best when everyone is on the same page, and has the same understanding about what "good enough" really means.
*Actually, I am thinking of switching Mining to Jewelcrafting or Blacksmithing. But I don't have a gatherer alt, so I'm procrastinating.
