End game just feels awkward right now. I wish there was more structure gear layering along the lines off:

Finish level 50 storyline at CM. No tomes reward.
Introduced to the first 8man Raid in Praetorium - drop iLvL60 Loot - put on Duty Finder - Reward Tomes
3 Dungeons (Wanderer's Palace @ 100, New Instance @ 100 and AK @ 100) that reward tomes to buy iLvL 70 gear.
Primal Hard Modes for iLvL 60, 65 + 70 Weapons.
Crystal Tower - 8man raid - iLvL 75 loot
Crystal Tower - 24man raid - iLvL 80 loot
Bahamuts Coil - 8man - iLvL 85 loot
Bahamuts Coil - 24man - iLvL 90 loot
Relic Quest for iLvL 90 Weapon (possibly finishing in Bahamut's Coil)

Doesn't seem too drastic and would easily provide more content.
