How do you run EOB Evangelion event without tank?

I have seen that some of the top guild runs are done without a tank and instead the healer does barrier but my party tried it and the barrier doesn’t prevent the laser from killing the player. We tried doing barrier at different timings and it still wouldn’t work, not to mention the barrier cooldown would sometimes be a few seconds short of some lasers too close together. Can anyone provide clarity or say if they’ve tried something and been successful?
