Again, that doesn't make mana more interesting in itself. Tanks are more mana-dependent for the reasons you mentioned (and even then, mana isn't something most tanks specifically itemize for), but that doesn't make mana more fun to have. If the mana got removed from the items you listed and tanks got their mana buffed in compensation, it wouldn't really change the appreciation of the items, because mana isn't seen as an extremely valuable stat there (that's not what I think should happen, though).
