Other viable composition of weapons for endurance?

Hey folks, could i have some advice from you?

this is my current build for PVP (arena mainly):

I'm running endurance, all I need are gloves and the cape (going for gilded and assault)

i'm testing fortitude to have more endurance and resistance, but my stats are perception->strength->dexterity normally

my focus is to have fun in arena (quite hard with the mass stun combo, but ok, i get it)

what could I have now? What do you think is a great synergy with bow or staff for my secondary weapon?

Thinking about GS/Staff or Spear/Staff

I'm not grinding for new gears for now, maybe some pieces of accessories, but I'll wait until t2 to spend lucent in gear
