Tier 2 Armor Tokens in Season of Discovery - Which Bosses Drop Them?

wowhead.com:

Tier 2 armor tokens can be acquired in Season of Discovery Phase 5, but their drop locations follow a very different pattern from Classic Era Blackwing Lair. Using the Wowhead Client, we've been able to gather locations and drop percentages for all of the Season of Discovery Tier 2 armor tokens.

Tier 2 Armor Overview in Season of Discovery

Tier 2 in Classic Era

In vanilla Blackwing Lair, Tier 2 pieces drop from scattered bosses in Molten Core, Onyxia's Lair, and Blackwing Lair, but all bosses dropped the same slot piece for all classes.

• Legs: Ragnaros
• Shoulders: Chromaggus

Tier 2 in Season of Discovery

While players may have assumed that the Tier Tokens for each slot would drop from the same bosses as Classic Era, that is not always the case in Season of Discovery. Some have remained the same, such as Nefarian and chest tokens, but there are many changes to the earlier bosses.

• Belt: Prince Thunderaan
• Boots: Broodlord Lashlayer
• Chest: Nefarian
• Gloves: Razorgore the Untamed
• Helm: Ebonroc & Flamegor
• Legs: Firemaw, Vaelastrasz the Corrupt
• Shoulders: Chromaggus

Other Sources of Tier Tokens

Another Tier 2 difference in Season of Discovery is that Tier tokens can drop from multiple bosses. Looking at the Wowhead Client, there is a «main» boss for each tier token with a very high drop rate (30-50%) and then several other bosses with 5% drop rates. As most encounters drop several tokens, it seems there is a high likelihood one token will be for a specific slot, and the other will
