Same.
I rarely play high PS anymore. The highest saved build I have is for the hard raids & Levi raid. It sits slightly above 15k, I think. It’s a huge ugly 5 wheeled slab.
There’s a satisfaction in using all your energy points & having a full synergy of weapon/weapon-fusing/module/wheel/cab/co-pilot set-up. You can’t get that much below about 10k. Having a pretty build that does that really makes the game more fun to me. It adds a level of complexity you cannot have at 7k. I get a good deal of satisfaction seeing my 12k build hit far harder than other 12k builds knowing full well it’s because all the parts are working together.
One of my fave builds at the moment is my Assembler build. Yes Assemblers.
Quantum cab for more Assembler damage.
Claw Wheels for more Assembler damage.
Power Unit for more Assembler damage… [edit - that one is not there for this build]
Hertz for more Assembler damage…
That first shot into an enemy’s weapon or cab is OP… and one-shotting enemies at the opening of a match just gives me tingles. The Gen-chat hate just adds to the ecstasy… and knowing I’m using one of the least loved weapons to do it… goose bumps. 
That being said, there’s also a level of simplicity and speed-of-match you can get between 5 and 9k that is also really fun. The matches are just fast, simple and have a ton of variety. Plus, the builds just LOOK better. When I play for hours on end, it’s never in a high PS build. It’s always in some flashy little thing covered in lights, exhausts, flares, holograms and some obnoxious chromatic paint.
For example, here’s one of my lightest builds… 4838PS, King, 2 Cobras, Cheetah, Bat, Maxwell, Genisis, Radio & just about every flashy piece I could squeeze in. At that PS, it’s easy to rush in, get some ding-a-ling to chase me, the drop a king & the two cobras on him. The cobras launch out either side on individual triggers, so they hit the king first, then get tagged from opposite directions by the cobras while I go flashing off into the distance.
Sometimes, that actually works. 




I rarely ever play much below 5k anymore simply because I end up spending all my time waiting for matches only to be plopped into a match where my 4500ps build is the lightest by 3000. No thanks.
And just because I know people need to hear it, bringing relics into a sub 10k PVP match is lame. Really pathetic seal-clubbing crap. You can justify it all you want, but that’s pathetic behavior. You’re winning, not because you’re skilled, but simply because you’re min-maxing & seal clubbing.
