Dying all the time, dont know what i do wrong

This league i decided to play scion for the first time, a build with fire trap and RF (using saboteur and inquisitor). Already i have died so many times. Just reached endgame and i die 2 times per map. Its ridiculous i know, even though i have experience in the game and played for some leagues. Currently my character is 66lvl, 2300hp,385 ES, 500 life regen per second, 82%(138)fire,75%(100)cold,75%(113)lighting res, 3000armour, and died in 1 sec from Drek in tier 2 map. I know i am not a pro gamer, but do i really need to be one to play this game? i try to dodge, while dealing 20kdps, what am i missing?

you should have 4k+ life already, thats the main problem
