The ALS training was created for the EMS Engine/Ambulance as it's the only unit requiring that training. If you really think the devs are lazy perhaps you should try coding your own game. Personal I think they do a heck of a good job writing code for a game that has several different versions of as well as creating new content weekly.
I do think they are lazy. Why? There has been so many bugs that have not been fixed. Creating the weekly missions is easy as can be, literally copy and paste, change some code. And bam you got a new mission. Sure they've made an amazing game, but there is also a lot of things they can improve. And I know it just doesn't a day to code something new in. Some things take hundreds and hundreds of line of code. But still they can provide updates of things they've been working on or something. Sometimes I feel like the game is abandoned.
