So i’m not good with too many skills in a rotation 
mainly just left click and right click and maybe 1 other skill to use on cooldown.
My highest level is a 96 DK that used Stupid Dragon’s Pre Krieg DK build but then all the Krieg DK’s were more complex and I didn’t know when or how to switch builds lol
Basically what I want is to know what build guide I could follow to make a geared endgame character that doesn’t need to use many skills.
You can always remove skills, like on [1.1.8.1] Voldrakia : budget Two-Handed Cadence Warder from scratch (SR65+) just use cadence and war cry (skip wendigo totem and the move skills)
I’d kinda be worried that the build would suck if I wasn’t using the abilities the build is meant to use though. I figured a build that was based around less skills would be better than that.
You see builds like some kind of recipe you have to follow. They are quite flexible. Otherwise, just play a retaliation build with lots of passive “retaliation damage added to attack”. Like a counter strike warlord 
Or primal strike warder, just use wind devil and primal strike. Easy 2 button build right there!
You can also use scripts: -play-piano-builds-with-ease-autocasting-of-skills-combos-faster-automatic-camera-autohiding-of-items-centered-inquisitor-seal-and-more-for-all-games/95616
Btw iirc there was a dude asking for a 2 button build a few days ago 
maybe aa warlord
Left click > RF
Right click > Movement skill
and War cry ( or drop it and go LoE & Scale combo)
Based from my experience, Warder is the easiest to go with only 2-3 button to press.
One of my Warder, this one only use mouse to play
