This is an excellent guide and hopefully a big help to many PLDs, both existing and upcoming who read it.
I am curious why you elected to use PCA in the TP set instead of a Fortitude Torque.
I could see it for extremely evasive targets perhaps like Byakko.
I think you could also do a little bit of discussion about WS sets. I know personally I use Hydra w/ Haubergeon for swift/vorpal blade (No excal) to maximize accuracy for consistency and enmity+ to get more out of them. This gear set is mainly worth discussing because you're already carrying so many gear sets so you have to work with what's available. Just curious to see your thoughts on WS gearing.
Thanks for the kind comments.
On PCA vs Fort Torque, it's situational, mostly depending on whether or not you have an Excal and whether or not you have Madrigal / Sushi. With an Excal, I'd favor PCA over FT for sure, as I don't think ~7 atk would out-do ~3 acc on a high level target where you want your Excal procs to happen. With a regular sword I'd probably recommend FT if you're using sushi (which you should, if you're meleeing) as you want to hit for more than 0. Again, there's no clear cut solution for every scenario, and both options are generally valid. In all honestly, I forgot about FT when putting together those sets, lol.
For WS gear it depends on what the goal of your WS is. Is it damage? Is it opening a SC? Is it gaining enmity? Depending on the answer, you'll be using one WS or another.
Generally speaking, multi-hit WS suck against high level targets where your acc is nowhere near capped (read this if you're bored, it's truly eye opening: https://rukenshin.livejournal.com/16428.html#cutid1
) and should generally be avoided.
Despite this, if you still want to try and land Vorpal/Swift on a HNM, I'd still favor ACC > STR over Enmity, as further reducing your ACC on a multi-hit will result in a much lower damage and thus less enmity generated than you'd get with less enmity gear but a better WS (see the linked post for more details on the detrimental effects of lower acc).
If you want pure enmity, gear for it and for +HP on slots where you have no Enmity and use Spirits Within. Personally, I never do this.
If you are on SC duty, you'll most likely be doing Savage Blade. Since your damage in this case is irrelevant, but landing it is the goal, I'd go full out on accuracy (bust out that Ohat, yo).
If you're WSing anything that's not a HNM, hands down use a proper DD set for WS, as it'll give the most damage and enmity.
Hope this helps!
