Recommended Armour?

[Karai17 0]

I am currently debating how much Strength I want to put into my Archer. I am currently wearing a School Uniform with Bellum Fortitude Mix which ends up giving me:

 

• 550 Defense
  
• 9.5 Absorb
  
• 75 HP
  
• 440 MP
  

 

I find this to be fairly desirable since I can hang out behind my Strength-heavy friends and spam my skills. The extra HP also helps when I get smacked in the face. Would this be a good armour to keep, maybe improving the mix at some point, or is the 400+ MP with the dip dev/abs that higher level armour would normally give?
