Dex Stacking Lightning Strike Chompion, does this look like a good idea?

(skip paragraph if you don't care about how we got here) I league started with a dex stacking Siege Ballista Hiero (shout out to POEGuy, great levelling and starter guide, 100% would recommend), but i got a bit bored of it and decided to look for something new. Since I already had dex stacking gear, I thought it'd be nice to keep building on that. Hollow Palm was my first idea, numbers looked decent, but not tanky enough. Yesterday I started cooking and after hours of wiki and ninja browsing, taco beef wraps, pob warrioring, crafting and grinding through the acts, I ended up with this bad boy. Nothing super original in the build, but haven't seen anyone combine them in a similar way.

Main features:

Hand of Thought and Motion, Fractal Thoughts - flat lightning and increased ele damage, Garukhan's Flight - buncha flat life per dex

Mahuxotl's Machination, Tempered by war - 100% cold and lightning taken as fire/chaos, max res to both

Doryani's Protitype - massive -lightning res to enemies

100% spell suppression and ailment avoidance, decent recovery

The build is still heavily work in progress, more like a proof of concept thrown together from things I had or could buy/craft from 30ish divs, but seems to be working. I seem a bit slow compared to regular LS champs, that and crit should up the dps pretty nicely. I expect to get a few 100 more dex, but I need levels and decent clusters for that. I think I'll path towards panopticon for the linger and life/jewel socket there, might even reroute the tree to get a longer path for the splits. Maybe Iron Reflexes to go full tank?

My question for the LS Experts, does this look decent for a LS build? Does it seem like a viable approach, or would I be better off with the regular version of the build? I'm not sure how much I've invested so far, but let's say 60 div ish? I'm also not really sure how to pob it for actual dps, some advice on that would be appreciated too.

If you have some ideas on how to make the build better, I'd love to hear them.

Thanks in advance and have a great sunday, Exiles!
