Only thing keeping more casual players from getting into raiding is the design of MMO progression these days. EVERY SINGLE TIER group gear makes older raid content irrelevant.

If group gear was ilvl 80 groups would still be forming to progress through 1-5 because it would be worth while to do. Instead if your not doing turn 10 raiding is 100% pointless.

Take it up with the people who champion content designed like this if you want to get into raiding.
