These are the additions excluding about 25 non-dropped items, 15 augments/bounty items, and about 4 in the high tier that have yet to transfer over from old bane. Also excludes things that already had bane on them, like Idol of Manslaughter (around 10 items total), which had their bane increased to match their difficulty/tier.
Some few more things might be added to the end tiers besides that 4, but given the quality of items and the extremely small number of mobs in the "tier" as the wiki describes it, a lot of the highest current banes are going to be in Saitha and Tur Ruj.

Tier is one factor in what got what and how much bane. Also taken into account was the quality of the item, difficulty of the mob, difficulty getting to the mob, how often that particular area was done, how thematically pleasing the bane was to the item and what sorts of mobs were being most killed in that specific "tier" of play.
Some banes may need to be fleshed out, but to say they were done completely arbitrarily and without progression is a bit insulting.
