Thermal Advice

[DocMidknight]

   I'm currently leveling a demon/thermal MM up but I'm struggling with how to build this particular pairing.  I've paired demon with dark, storm and cold with similar builds to hit what I kinda want outta my MM's which is ranged defense at the cap and s/l resist at the cap but with thermal I don't see that as happening so I'm wondering how should I build thermal up, what is the recommended or favored slotting ideas. 

 

 

   Appreciate any help.
