It's akin to a designer going 'sure you can get the gear by grinding on the hardest Metal Slimes in the game but you could kill level 1 blue slimes instead! And it's quicker!/game designer genius
It's not good game design. It's not about playing different aspects of the game, it's about every part of the game being rewarding to the amount of effort needed to do that content. If you want to put some BIS gear into dailies, it should be akin to having to trek 5 zones over to find a mcguffin not shown on the map then having to kill an army worth of mobs hoping a specific mcguffin drops that leads to a scenario you can fuck up many times in (like the mage towers in legion) equalling in a BIS item for one or two of your slots at the maximum. So that it doesn't make raiding feel pointless in the long term.
I can't believe Azmon is against the 'do the raid every week' design philosophy that worked for many expansions. If a boss is going to drop what you want was pretty much the hook to keep you coming back week on week to kill it with your guild. To be against that is to want to kill raiding and guilds altogether, in my view. Content should have a end for sure unlike the current titanforge bullshit, but the way gearing was designed to begin with worked well enough that you either got bored eventually or got everything and moved onto an alt if you wanted to. The idea of only doing a raid once or twice because you don't need to go in there again makes the game even shallower than it is!
