Play the skills/masteries you like/invent build on your own, don’t read any build guides.
Since you can respec your skill/devotions points pretty cheaply, there’s nothing you cannot fix in case you screw up.
It’s boring to play a perfect build that doesn’t have any hiccups along the way (I mean too little defense or something like that)
And if you for some reason feel like full respecc, don’t want relevelling, you can do that easiliy with i.e. GD Defiler.
