This is not WAR exclusive problem, neither tank exclusive.

- PLD, the "magic tank", starts using spell in its rotation at 68, with mobility at 74
- DRK has TBN at 70 and until recently he used to have 2nd AoE combo at 70+
- BLM is regarded as "trash until max level"
- DNC gets DP at 60.
- WHM gets lilies at 52, but they're DPS loss up until 74
- Most non-tank jobs gets their AoE way too late

The list goes on. Only few classes have solid core at 50-60, and WAR is one of them. Hopefully 7.0 finally addresses this problem for every jobs.
