Tobold's post on whether raiding is obsolete got me to thinking about my own experiences.
One of my reasons for raiding is as far as PvE is concerned it is the only way to have a ready made group for doing things.
I quit the game on my very first main because at 60 there weren't many raid groups and there was nothing to do at cap if you didn't raid (leveling an alt was a foreign concept to me at the time).
Before the LFG tool, I could log on - and playing tank/healer I didn't have much trouble finding a group - it often took time.
But by raiding with a guild, I knew when I logged on the group was made for me. All I had to do was show up.
The same with PvP battlegrounds, I could just join the queue and a group would be put together for me. Not a good group, but a group nonetheless.
Now with the LFG tool, groups are put together for me and everyone else for PvE. I can play an alt get it reasonably geared, play another alt and do the same.
I can stay out of the raiding scene altogether, because I don't need it to fulfill my multi-player need.
I'm not saying I'm going to stop raiding. I'm just having a lot of fun using the LFG tool on my alt at the moment.
