(I guess one could argue that programmer mode should include IEEE-754 floats, but I'm fine with that mode being limited to integers, it's plenty useful already. But it does require switching to another mode if you need a calculator to calculate floating point numbers)

This is reasonable, but what is incredibly annoying is that when you type in a number while in Programmer mode, if you then change to Scientific mode, it blows away the number you typed in.

Of course that doesn't mean it should have been loading so inefficiently regardless.

Am I supposed to play a multiplayer game when it takes 10 minutes to open and another 5 in queue and then few before it starts?

Blizzard launcher downloads 137 MB to launch some games EVERY time. In fact some game did not even start, probably due to mismatch of version on the patch server and game server. Nobody in Blizzard seems to notice nor care at all. The whole management board should be fired.

I remember paying 10 dollars for starcraft remastered and it plain didnt work, because blizzard doesnt bother to fix their battle.net app (all they did was try to rename it to blizzard app). Now statcraft bw works, but it didnt for few weeks.

You finish your work, want to start the game and it cant even start fast.

It still feels like they just break UX to support touch devices better than older UI would. I might just be showing my age, or out of touch, or perhaps because I only use Windows for work but I have no intention of ever using touch on a device running Windows. My laptop screen support touch and I turn it off as it's and unexpected behavior to me (if I touch my screen I'm probably just pointing at something/showing to another person).

Touchscreen-first design does this to apps ¯\_(ツ)_/¯

Technically incorrect, I don't ;)
