The titans were the original Gods in the Wow universe - they have always felt mysterious and leagues above us mortals.
Since they added the cosmic forces lore, we now see that each 'power' should have its own titan equivalent.
The eternal ones never felt on the same level as titans while playing shadowlands. Sure they may have been drained of some anima, but the fact we just hang out with some of them in their house kind of downplays their stature.
Are the wild gods really the same level as titans? Who was supposed to be in charge of Disorder before Sargeras took it? It would be cool if some of these deities looked really unique and not just big humans with fancy armour
