I don't know to be honest,i finished the game and will try it out again after all the DLC is out....maybe. But judging by the core of the game,yeah it is pretty easy and patches won't do much about it.
After level 12 or so difficulty goes down the toilet. It's select-all auto-attack every time, all the time.
The game's difficulty curve is really ... weird, especially on PotD, even for a cRPG with a big level spread. In fact I haven't been able to beat some of the fights on Maje Island without hiring mercs, thing feels like I brought a butter knife to a gun fight. OTOH once you're a few levels up and are able to choose what to do and when, it flattens out. And once you hit the high levels, it turns into a snoozy kind of grind.
I really wish games like this would make character development more horizontal and less vertical. This has horizontal development too but mostly it's just inflating numbers. That's just inherently crazy difficult to balance when the scope gets this big.
