New Unreal is a an all around miserable experience.

All of the aoe's are heavily telegraphed. There is no untelegtaphed spread mechanic in sephirot.

For earth spike spread there is a distinct sound telegraph and visual light pulse. For da'at he visually pulls energy into his chest with a charging sound.

Pretty sure by "no telegraph' players are referring to there not being ground indicators of where the damage will be. This is pretty general, and common knowledge with players.
