Ninja = rogue + 5 abilities

rogue = thief

Ninja = thief + 5 abilities

What raid tier role currently exists that is different from their base in anything but name (except sch since it goes form a dps to a healer)

pug / monk = pug + dragon kick (added into pug rotation) + shoulder tackle (a movement ability) + a dmg buff.

thm / blm = thm + flare and some utility abilities



So your saying because it gained the flare ability it is a completely different class from thm? And because Rogue (thief) gains a couple abilities it is no longer going to use the other 17 abilities it has?

It's more accurate to say your playing rogue(thief) at 50 than ninja at 50. since 17 of the 22 abilities (and all the passives) are from rogue(thief)
