So basically your only argument for keeping day 1 hard node only farms is that you like them. That's your oppinion and that is totally fine, but as an argument it's sort of weak and easily dismissed. Just like some/many of the arguments in favour of increasing the availability for that matter.
However, agian i'm a bit biased, there have been alot of solid arguments in favour of increasing the availability wich in my oppinion outweights personal preference (of what i assume to be the minority). So i'm not saying you're wrong or you should change your mind, it's just that your personal preference doesn't benefit the game for all players. Atleast, i haven't seen an argument that made me think it is in fact beneficial for the game and it isn't just a personal preference. Maybe i've got tunnel vision, but i can't imagine more players prefering day 1 hard node only farms over increased availability than the other way around. If that were to be the case it would be a good reason to keep them though.
The reason i think you're in the minority simply comes down to people being selfish actually. Not alot of people have them all farmed and wouldn't mind it if they became easier to farm. I also assume there are more players that wouldn't mind increased availability eventhough they have multiple hard node only farms at 7* than there are players that don't want increased availability regardless of them not having multiple hard node only farms at 7*.
