Basically the game has issues at pretty much anything more than 1920x1080.
Things like clicking the primary and secondary colors in the costume creator gets wonky.
Base editing is almost undoable.
I'm running at 6480x3840.
What you wanna do if you're looking for "Durable", look to go almost pure Resist, and toss a tiny slathering of Defense on there. It'll help offset giant alpha-strikes, then, if it gets Debuffed you just balls your way through on straight Resist.
Here's a build just to give you ideas about some of what's possible.
For things like /windowscale NAME 1.50?
I know for the various trays.
The main 3-tray interface is /windowscale tray
First tray after that is Tray1
And so on and so forth.
And here's an example of a Mo Durable type build.
Again, just an example, could probably be tweaked for better synergy, stats, etc.
In full "up" mode (Rune running) the only differences between you and a Stone Tank is literally lower HP and Regen but higher Damage output.
Here's a basic example.
Not claiming this is the toughest.
Not claiming it is the best.
Just saying that it performs very well when stuff's busting it's butt to kill you.
Look up my Invuln Framework thread.
Grab the Brute template.
Fill it in.
Nigh-upon godhood ensues.
If you don't mind giving up the Recharge, look up my "Mo Durable" build. If you get yourself familiar with the Framework build, adapting the Brute Framework template to a "Mo Durable" is straightforward.
I didn't say "going for defense".
Because they obviously didn't.
I'm saying that greater (not perfect) Defense is one of the desirable side-effects of Agility.
The Charged Armor complements the Defense with better Resistance.
Makes the build much less prone to "eggshelling" from anything that can reliably crack Defense.
