They do nothing but replace content instead of EXPANDING it.
a year later we still only have 4 relevant raids. The rest are replaced with soloable gear. At this point in the game end game should look like...
Group (ilvl 70) > CT1 (ilvl 80) > CT2 (ilvl 90) > Coil 1-5 (ilvl 100) > Coil 6-9 (ilvl 110) > Coil 10-13 (ilvl 120)
Instead group gear skips you right to the end and makes all previous turns irrelevant.
