im only 61atk/59str/48def/59hp(71 combat) and i keep getting 130+ fire giant tasks, at my level are they even worth doing?

Cannon and pray melee

but what if i want to level my melee im trying to get 65/65 for warriors guild

Cannon them while meleeing them bro. You'll get decent range/melee exp. You could also just solely melee them with prot from melee, but I think this method would be more expensive

lol i didnt realize that was a thing

rule #1 with slayer cannon everything.

I don't do Slayer unless I can cannon it.... usually skip what I can't lol
