So I started Super Hard and I am running into trouble. Any SH missions that have a time limit is pretty much impossible for me (Save for the easy triple Banther one).

I am currently level 115 force.
Using the 2234 t-atk Rod with 16% fire tech bonus.
Attachments are:
-Prayers Form
-Stamina V
-Millimeter? (The 6% version of Ancient Oath)
-16% wind tech bonus

Techs I use are 21 Rafoie and 21 Sazan. I alternate between them for Tech Arts JA Bonus. I also use deband, shifta and resta.

Skills are:
Tech Advanced + Tech Arts JA Bonus = Tech JA Advance
Flame Mastery
Wind Mastery
Fire Resist Down
Wind Resist Down
Tech L Charge
Tech S Charge
Elemental Weak Hit
Flame Weapon
Wind Weapon
GP Burst
GP III (working towards GP IV to combine with GP Burst)
T-Atk UP 1 + T-Atk UP 2 = T-Atk up 3
GP Charge Revival

Going to get more Memory Fragment J's so I can alternate between 2 techs of the same element for all elements.

Honestly, I am not sure of what I am doing. Any tips for improving? Also, any recommended missions to level up in?

Thanks.
