You need more than one GUR (3 at the minimum, 4 is pretty optimal, any more is questionable worth) for elemental hall. Having 3 makes Elemental Hall Intermediate a breeze if you have good shielded SR/HSR as long as you have one in each team.

For Advanced having 4 is hugely important. I haven't played advanced myself but apperntly the AoE wave that hits does as much damage as FAW AoE. EH Advanced basically requires 4 different FAW teams which is why for late-game players going for 4 + GUR FAWs in some events is pretty important.
