Why call it a "catch up gear" when it really doesnt let you catch up

UPGRADE SYSTEM

• Hero upgrade track length increased to 6 (was 5).
• Myth upgrade track length increased to 4 (was 3).
• Crests are now currencies and will no longer take up inventory space.
• Fragments have been removed. Sources that previously awarded fragments will now award crests.
• Once a player has purchased all possible upgrades with a type of crest, they can visit Vaskarn in Amirdrassil to exchange those crests for higher level crests.
  • For example: Using Season 2 item level numbers, players would become eligible to trade their Whelpling Crests up to Drake Crests when every gear slot had reached item level 411 or higher. Trading up to Wyrm Crests would become available at 424 (again, in every gear slot, using the same rules as crest redundancy), and trading up to Aspect Crests would open at 437.
• PvP gear can now have its PVE item level upgraded with flightstones and crests (was Honor). The PvP item level will remain unchanged.
  • All PvP activities will reward flightstones, and crests can be earned from rated activities.
• Players can earn 90 crests of each type per week, which is enough to afford 6 upgrades of each crest type per week (was 10 upgrades).
