need some advices

i Play a EA marauder. its a really cool build, but i have a big Problem in pvp.
i Need a few time to stack the arrows, 4,5 attackspeed atm, but i guaranteed loose if the enemy is a meele with leap slam or something like that. all other meeles i can handle with bear trap x multiple traps. if they locked i have enough time to stack EA.
But that doesnst work if they use leap slam

i have a 4L item left in which i can put some gems, so whats a good idea?

Last i saw a Player with a spell totem and frost wall, a really annoying Setup

what are other good choises to Keep the enemy on distance?

CoDT, cold snap, temp chains, ice wall
