I've been using nothing but SnS this time around and loving it. Fast, extremely mobile and being able to use items at all times is great.
I largely used different Elemental SnSs early on, whatever the target was weakest to. Then I grabbed a few status Swords like Deathprize, Sleep SnS from Hororo-Horuru, and the Dreadqueen poison blade.
Once I jumped online, it was insanely hard to use anything but the Dreadqueen armor set with the Deathprize. That is what I am using 90% of the time now while I farm up other sets. The paralyze is just too good. If it is a monster that is immune to Para, or extremely resistant to it, I'll go back to the favored element or in some cases Raw.
I am looking into a good blunt setup next.
As stated, Oils are a little OP. I usually start with an Exhaust oil and if no other weapons are up in the face I'll use that until KO. Then I will usually switch to Affinity or Partbreaker oils. If I need it, Mind's Eye Oil is indeed an amazing amazing thing. Kirin for example... no bouncing off her silly dumb face and tail.
I mainly use Adept so I get the lunge back slash attack and use that for an infinite combo. The dodge from Adept into a lunging uppercut means I mount a lot too. With striker you no longer have that dash backwards and run in attack, so I'll just break off at the end with a side roll and get right back to hacking.
