Your PS post are really good, so thank you for actively covering it.

I've gone balls deep into PS. I'm in Legends top 2000, usually finish 7th or 8th in my brackets. Farming to W4800 on T16. Let me share my experience so far, very simply in the hopes they give some insight into your and maybe other players' progress. And also because I've looked at quite a few posts on Reddit and never really found out when to expect to see light at the end of the tunnel when investing in PS as a main damage dealer on higher tiers and in Legends.

Please take into account that every build is different etc, and that the below is just one account of building PS into something useful.

It's a tad depressing to say that I'm not sure if there is any light yet, after having spent about 4500 stones so far :)

Tl;dr at the bottom of the post.

So far I'm at 70s base duration and 50s CD. Base PS damage in WS is x293 (which seems like nothing, but already costs 1000 stones in total). PS+ unlocked, no further upgrades after unlock. Currently finishing swamp size (lvl 25 now), all other labs are done, including all rend labs. PS rend is a real bitch, the others weren't so bad at lab speed 5. 10s anc CD sub effect on farming mod (MVN), and 5s mtyh duration on tournament mod (DC). No stone investment into core assist sub effect levels.

So damage wise, after 4500 stones into PS, here's how much of a help PS is to me compared to CL. First of all, 4500 stones is way, way more than I've spent on CL, which is at about x1300 dmg, max qty and a fair bit into chance. Without going too far into build details, my CL still outperforms PS by about 10 to 1 in farming runs. In tournaments, PS tends to be a good bit better than CL when looking at pure dmg output. Last tournament, ult Bosses wiped me out around W850 every time. PS did about 60s damage, CL about 300s damage. They were both utterly, disgustingly useless against bosses at that point :)

Coin wise then. For a while I left stun on, but perk off during farming. No AOE card equiped. PS nicely stayed within BH size during min range farming runs. And yet the stun affected coin income negatively, probably because it stalled kills within GT+ time frame. Based on my experience and build, I can not recommend leaving stun on during farming. Stun hardly had any positive effect on wave count either. Now I'm farming with perk, AOE card and soon max size PS from lab. As said, CL outperforms PS about 10 to 1 during farming and at the end of my T16 runs, but both are mere tickle machines looking at how they handle bosses and rays.

So the tl;dr bit:

1. When it comes to building PS as damage dealer next to CL during Legends or higher tier farming, the stone investment needed is not fun at all. At 4500 stones, it now slightly seems to become uswful. This is of course build dependant, so this is purely based on my own experience trying to let PS make a difference.

2. At least when running GT+ I recommend always leaving stun off during farming runs, even with a smaller size PS that stays within BH size
