As soon as you said 8-9 FPS and high ping I immediately knew you need to go earth build. Its the most friendlist with ping. Its also best for PvE, too. Wind is fun but you need good ping and gear for it to matter. I'm an earth summoner.
This is my build: http://prntscr.com/h1k1ap
Weapon doesn't matter much. Just go baleful. Badge wise Magnum or Alluvion. Alluvion if your ping is really high. Mystic badge enigma or revelation. I use revelation.
