Collection of 7.2 Mythic+ Changes

With 7.2 there were a couple of Mythic+ Dungeon changes. Some of them are documented in the patchnotes, some of them seem to be undocumented. Is there anywhere a collection of all the (undocumented) changes that came with 7.2 affecting Mythic+ Dungeons? I didnt found any, so i will try to gather the changes in this post. If there is something similar already, let me know.Below you can see the documented changes and all changes per dungeon i encountered so far. I will add your infos too. If someone confirms my encountered changes or yours, i will add a "[confirmed]" behind it. Thank you all for so many responses to this post! I will update this further after my raid is done. Until then i created you a Strawpoll to get your opinion how the new +10 feels vs the old +15: Strawpoll Documented Changes:from official patchnotesRewards:Mythic Keystone dungeons now award gear up to item level 890 at keystone level 10, and now award gear up to item level 905 in the weekly Challenger’s Chest (at keystone level 10).Bluepost with details on this:After Patch 7.2 has been released, the minimum item level of the rewards found in the end-of-run chests will be as follows:Mythic 2-3: 870Mythic 4-5: 875Mythic 6-7: 880Mythic 8-9: 885Mythic 10+: 890(Note: bosses in Mythic Dungeons run with no Keystone active will drop item level 865 gear.)The minimum item level of the rewards in the weekly Challenger’s Bounty chest (found in your Order Hall) will be based on the highest difficulty Mythic Keystone dungeon you cleared that week, as follows:Mythic 2: 875Mythic 3: 880Mythic 4: 885Mythic 5: 890Mythic 6: 890Mythic 7: 895Mythic 8: 895Mythic 9: 900Mythic 10+: 905Artifact Power rewards from both Mythic Keystone dungeons and the weekly Challenger's Chest now continue through keystone level 30.Artifact Power rewards for Mythic Keystone dungeons have been adjusted: Longer dungeons, such as Halls of Valor, now award a proportionately higher amount of Artifact Power.
