M+ loot this week and next week question

[Languse-nemesis]

I read the bluepost talking about the week of Jan 21, but it looks a little confusing for me.

@Kaivax

Season 4 begins.

• Item levels increase by 30 for rewards from seasonal activities (dungeons, PvP, World Quests), and can now be corrupted by N’Zoth.
• Mythic Keystones will downgrade by 4 levels.
• Dungeon difficulty is increased for Heroic and Mythic difficulties.
• During this week, end-of-run rewards from Mythic Keystone dungeons and Rated PvP are capped at item level 445 (for Mythic +6 or PvP Rank 2).
• Mythic Keystone and PvP chests that are opened this week reflect Season 3 rewards earned the prior week, and cannot be Corrupted, but may Warforge/Titanforge.
• Item level improvements for weekly rewards now extend to Mythic +15, which awards an item level 475 piece of gear in the weekly chest to be opened on January 28 or later.

Correct me if I’m wrong, but this is my understanding:

• End-of-run rewards will be capped at 445, so if I complete a +15 will be the same as a +6.
• Weekly chest that we will open in Jan 21 will contain a piece of gear scaling up to +10, can be titanforged but cannot be corrupted. The ilvl will be the same as what we already had before (a +10 will give a 440 with chance of titanforge).
• Weekly chest that we will open in Jan 28 will contain a piece of gear scaling up to +15, cannot be titanforged but will always be corrupted. The ilvl will be increased from before (a +15 will give a 475 corrupted).

Am I missing something?
