Tectonic slam of cataclysm bug (visual?)

even with 10 endurance charges spent it doesn't branch or gets bigger at all.

the damage works and it seems like enemies might get hit by the actual area so it could be a visual bug but i can't tell for sure

tried with and without the MTX and there is no difference

A lot of bug report threads are talking about this. It's been bugged since league launch and GGG has so far been silent regarding it.

Some people report that the damage is less. I'm like you. The damage and AoE seem to be fine, but the added AoE is invisible and farther away monsters seem to be dropping dead by an invisible force on a 7-charge slam for me.
