My concern is with minigame removal in a general sense

They mentioned how they're definitely removing Rat Pits, and they're really considering removing Mobilizing Armies, which I eventually would get over, but my concern is with minigame removal in a general sense. If they're willing to remove any minigame that's dead like Mobilizing Armies, does this mean they could potentially do it for any minigame that people don't play?

For example, there's still some minigames that don't require other people to play that are pretty dead as far as I know. Just I like Mobilizing Armies, I like Vinesweeper, and Gnome Restaurant, and many more minigames like them. If the only standard for a minigame to be removed is if its dead or not, I can't say I agree with that. 

If minigames can't be reworked to make people play them again, what's the point of designing future minigames? Won't those become dead aswell? I just think solo minigames, dead or alive shouldn't simply be deleted as easily as minigames like Rat Pits/Mob Armies.

I don't like the concept of D&D's or mainly the fact that we only get D&D's instead of minigames nowdays. Minigames allow us to have an alternative to training the skill whereas D&D's are too limited for a good amount of play time. 

Converting them into D&D's would be a step-down for me; however playing against the clock or an AI system is something I'd be down for with most minigames. Mob Armies could have an AI system, Barbarian Assault could have one, Trouble Brewing, and a load more of them. I just don't think deleting them solves anything. It's going around a problem that eventually they're going to have to fix in the long run.

The issue simply is they released two totally redundant minigames 2014, whose rewards could have been perfectly distributed at existing games. Furthermore they have created several interesting items which could make minigames more interesting, but those had to sacrificed to have them available at MTX (wicked pouch, every single skilling set released the past few years (except the exoskeletton),...). Minigames need to be fun and they need to be rewarding to have them being alive. A D&D on the other hand just needs to give out a certain (more or less good) reward and it is played. And as D&Ds are limited anyway regarding how often you can play them, they can also be more generous just with xp.
