The problem with locking the highest ilvl gear behind raiding coils was all it did was ensure hard core players have shiny high level gear to lord over the casuals. What SE did from 2.2 onward was an MMORPG No. Without a variety of ways to obtain the same high level gear a divide was created between casual and hard core players. Hardcore Gamer are able to progress through Coils and get all their BIS and ilvl 110 coil gear in 6 weeks. Mid Core players get screwed over because by the time they get their BIS and ilvl 110 gear a new set of gear is out in a week and Casuals are simply left to play Coils just to see the story and unlock the next Coils.
