Act 1 is not that easy, considering you are level 2-3. There are fights which is difficult depending on your setup, no doubt. But I would say from act 2 no fight is difficult. I dont even allow for talks I press the Attack option and get swarmed, and stil manage. Of course knowledge of the game mechanics, itemization etc helps. But I opt out of using too much area of effect for a reason.

Act 1 I think is fairly balanced. The Goblin Stronghold fights can be devastatingly difficult. But act 2 and above all act 3.

It is cool to recieve all items you have in this game but then the game needs to be balanced around this. Act 3 npcs and monsters needs their hitpoints doubled, at a bare minimum.

Without using anything special I burned down "Spoiler"....Savorek in 1 turn. Just using melee.

I mean we walked through the game on 2 players in multiplayer. We gave up in act 3 as it was too easy, restarted and need to, in order to have fun, limit our options. For example, no multi classing and avoid certain items, or the challenge is simply limited.

But I do say that act 1 on Tactician can definately end up in a few reloads in fights. But thats just fun.

And I play the game without haste, buffs, elixirs etc. There is no need. If you rush headfirst into certain fights yes you will have issues.

The only thing I ask for is that we can have an ingame option to increase enemy health bars. With all items aqquired in this game (some aqquired at level 5, 6 already is items you maybe will be lucky to find ONE of in a level 16-20 table top campaign). I love the items, they are cool and great made, the entire game is just rock solid but all I personally ask for is an option to increase enemy health in order to provide a more challenge for us that actually do like to min max, and use whats available.

Just take the dual crossbow ranger Hunter/Thief, as an example. Throw in a level warlock, since hex procs double, triple proc on your sneak attack and your colossus slayer. But its not needed.

Risky Ring as an example on a warrior multi classed with rogue, and the crit items this game has, its just crazy damage numbers you can accomplish.

In our multiplayer session I was at a point playing as a ranger Gloom stalker and assasin. We had to respec my character as my playing friend was not involved in fights, if I got a surprise I would clean up an entire group of enemies deep in act 2 before he even took his first action.
The examples are many.

Sometimes you are unlucky and indeed must reload a game. happens to everyone. But it happens literally never half way act 2 and forward.
