These are my current sets
Personally I use a Sindri and Caglistro's rod. (Caglistro's main hand if using Kclub)
Working on a Mjollnir,
but can average about 10k Hexa strikes inside abyssea, without the Espial set just fine.
Don't missunderstand, Mjollnir is a good club, but isn't required to be a functional Melee WHM at this point.
I know some of these sets could benifit from HQ rings etc. But It's just personally what I use.
ItemSet 313600
Personally I swap between using MND earrings and the Tati Earrings.
Non ilevel content I prefer to hit up the MND earrings.
ItemSet 312221
Recently updated my sets to this level. Needs some tweeking here and there for Kclub. Personally if I actually owned a Kclub, the Back, waist and neck would be changed too something like Rancor Mantle, Goading belt and Iqabi Necklace.
ItemSet 327867
Speaks for itself, At least one ring can be changed to Patricious ring from AAEV. Or you could play around with it futher and swap to the ring from Arch Diablous.
ItemSet 312223
Again the earrings can be Tati, just depends on your preference.
Loosely, I solo Dynamis and Salvage II like this as well.
For people who don't have access to some of these items here are some alternatives. ALL of the suggestions were pieces I personally have used, or know of which I could of used as Alternatives. I do a lot of end game, so getting the higher teir stuff is easier for me.
Realmrazer:
Use the Weatherspoon Body +1 for this set. I used it before I got the Vanir body, and it functions just as well. Could also use the MND cape from Tchukka if you want, and some of the Gendewitha pieces work as well. Such as the Gendewitha Galoshes +1 for Feet. Also the Buremete hat with MND Augument on it DOES have 1 more MND than my current piece. If you can work on that.
Some people use the DA Attack earrings and say that they work just as well, but I havn't tried or played with them, so I can't surely awnser.
TP set:
Can use the Theo. Body +1 or Espials body (If you want Accuracy) as an Alternative to the Chausable. Ammo you could use Flame Sachet if you cant pop into a wildskeeper rieve of snag one of the AH.
You could also use a Vanir Battery, if your willing to throw out the gil on it, and you aren't using a Kraken club.
Again, instead of Battlecast, you could Use Bokwus boots with Accuracy Auguments on them. (Type C)
Pants alt. You could use Espial, and the same goes for the gloves as well, but the Bokwus is just my personal preference. All with Type C Auguments.
Accuracy set:
The belt can be replaced with a few other alternatives, none of which i can name. Same goes with the cape. Although the neck has lots of alternatives such as Peacock charm. Ring wise, Enlivned comes from Sparks, it isn't too terribly expensive. You could also use the club skill ring from the Arch dragon in Dynamis Bubu.
You could use the Espial pants, but the Accuracy diffrence is quite some, And Bokwus boots as well if you cant get Battlecast Gaiters.
Hexa Strike:
I don't tend to use Hexa strike anymore, However, you could use the whole entirety of the Espial set, (Such as Skjalf Show cased above). You could swap the earrings to STR earrings if Tati earrings are to expensive. Or even use the DA Earrings from Delve, it just depends on preference.
Neck wise and back wise there isn't really an alternative which i can speak of. But you could use Caudutta belt as well (The WS accuracy belt).
Ammo wise you, again, could use Flame sachet.
