It's min-maxing, blizz has stated in the past that no fights are designed around having those consumables on you, and frankly the buffs are so tiny compared to your overall stats that I doubt they really make a difference.
Unless you keep wiping on 1-5% of boss hp, consumables are just a waste of money :P
