The coming changes will make azerite power much more pleasant to deal with, however I think the system is inherently flawed.
Currently the amount needed is reduced by 30% every week (except for the few weeks at the end of a raid tier when they arbitrarily chose to pause it)
This makes people feel like they lose hard earned progress, thus demotivating people from farming it.
However if you wish to be competitive with the others in your guild you are required to keep the grind up.
There is no quicker way to burn out on a game then to continually do something you do not want to do.
In legion you increased what you got instead of reducing what you needed. This caused a less severe apathetic feeling, but it was still an issue there.
When you can play 100 hours this week to get azerite power or wait three weeks and only need to play 35 hours to get the same necklece level, people will get demotivated.
The system would be much more healthy if you had a weekly cap for azerite power similar to conquest cap, While at the start of each raid tier you bring everyone up close to where the cap is.
On the content front I find it really hard to muster the will to play to keep up my necklace with my guild.
Personally despise world quests and islands, I find them both mindless and boring, islands especially so because they all feel the same.
I find m+ tolerable but not enjoyable, I did allot of them in Legion and have done quite a few in BFA.
I think dungeon design was a better in legion, there is now a bit too much trash.
I also think m+ would be more fun if tyrannical and fortified were removed while bosses get a small buff because baseline they feel weak compared to trash.
The reason I think these modes should be removed is because boss fights feel boring and too long on tyrannical while trivial on fortified.
I also feel the highest rewards are not good enough while the brake point for the highest ilvl gear is way too low.
This culminates in mostly doing an easy +11-14 once a week just to get my weekly chest.
If the ilvl cap from m+ was the same as mythic raiding -5 instead of -15 it would not feel pointless on the item front.
It would feel allot better to grind raids and dungeons aiming for a bis set rather than to be on an endless treadmill hoping to luck out on a titanforge and getting azerite power that will effectively be removed over a few weeks.
I like raiding, but I do not like being pressured to do content I do not like because I am expected to be neck level x before the release of the next raid. (IE, you have to have concordance X or you have to have neck level 38 such that you can use the new items you get)
I encourage everyone here to please share what you think about the current systems and the upcoming changes.
now grind the tillers, each one of them 
or TBC puts a tabard on and have fun.
