I never trained much of those because I was always saving my credits to train a lot of AL. I don't get many artifact drops and losing a lot of stamina when I'm playing really sucks. It gets to where I can notice a difference. Sometimes, I have to stop playing and that's no fun, especially when I'm in the mood to do it.
The smiley face changes, too. Stupid smiley face.
I'm noticing the stamina lose too as I do arena rounds from End Game and after. For you, AL is all you would need I guess, but it might be worth it to train Scavenger and Archeologist to get those drinks. I have yet to use any, and I never see them in the Bazaar.
