Too hard ? Yes - it was at least with the original Divinity 2 game - and that for rangers, this was my personal experience.
I don't know how it is today, since I don't have DKS.
One of the points is that Powergamers are easily attracted by Action-RPGs - and Powergamers ALWAYS distribute points so that they'll get the most combat-heavy character. No matter whether using magic or close combat or ranged combbat or whatever.
Powergamers are also quick with computing which skills give the best results for their price - I call this "points shopping" - and they re very good in maths, computing everything out ...
And they know what they do. They often have a distinct plan on how to develop their character into the most powerful direction.
The problem with this is, that me, for example, I'm not used o this kind of thinking (in PG terms). I want to play a riole, not play a mercenary (that's why I absolutely LOVE Drakensang 2 !!! - in contrast to the rather combat-heavy Drakensang 1), who is an Über-fighter, but lack so much in (mot implemented) social skills he would be thrown out of any noble society (and OF COURSE he woul come back, destroy the whiole castle and let leave nothing but blood & bones behind BECAUSE people were complaining about his ABSOLUTE lack of social behaviour !).
And so, since I'm not used to this kind of thinking that any action RPG implies (especially the way of the PG in terms of thinking), I'm not good at distributing points so that my character becomes the Über-hero who is able to defend anyone and anything (and degrade anyone who complains about "my" lack of proper social and intellectual behaviour into blood & bones).
Which makes my chracter weak.
My result of this is that I should rather *not* play action-oriented RPGs - but what choice do I have ? The current RPG world delivers nowadays almost nothing but action-oriented games !
So, now, I'm plying Drakensang 2 for the 4th time. I LOVE it !
And a few weeks ago (if I remember correctly) someone came into he official Draknsng forums, complained what kind of utter crap Drakensang 2 was, no replayability whatsoever (despite me playing it through for the 4th time) and tht the fights were so booooringly easy ... Meanwhile - as he wrote - he was playing Drakensang 1 through for the third time, found its replayability excellent (I found almost none) and all in all made very clear (though rather implicitely) that he was a powergamer ...
I assume that i must turn towards the Indies if I want not-combat-heavy RPGs nowadays ... Action is the main path, the highway, and non-combat is the niche that no-one works for ...
