No one is forcing you to use consumables. I have played the EA through with three different classes and I have used just one speed potion in spider boss fight because I would have died without it, that's all, no other consumables, not a single one. I don't understand what's the problem, you don't like to use consumables then don't, but if you do, you have the option to do so.
The problem is the game would be more fun if combat was balanced around the idea of limited rest and other principles from D&D 5e. Ramping up difficulty and adding in cheese doesn't make combat fun.
I've played through the game several times without consumables. In patch 3 and 4 combat has been stale and there are many threads on the topic for why it is stale. for example. Some more,and another.
