We are quite similar it seems. Playing since release, around 3.8k hours(I think?), 13.5k achievement points. I never tried raids as well. For the exact same reason. Don't like that I really need to plan my gw2 evening regulary, cause I already got other hobbies where I need to prepare for an evening. Basically I'm stuck on T4 fractals and can accomplish them without that much trouble on different classes. The only option for me to do raids right now is, cancelling everything else and really focus on gw2. That's sadly not my way right now.

Even so. I'd love to complete the raids, I'd love to get legendary armor. Guess I wouldn't have problems with those mechanics since I love them from what I'm seeing in regular raiding streams.

Just don't think too much about it. Play "your" game in the way you enjoy it. If you have doubts about something, don't do it. Yes we both don't get the experience from raids. But that doesn't mean too much. Who knows...maybe I will try in the future. But until then I chase after more legendary weapons, my backpack and other targets :D

Just have fun.
