Without compensation that change is annihilating all the channeling builds that currently work thanks to the autocasts.
The problem was easily solved if they had made DW twice as strong but the buff limited to all channeling skills … and Etched Sigil three times as strong but only affecting channeling spender and autocasts from ES.
If they fear ES + Hydra, they could have excluded Hydra from being autocasted. There you have it…
That would have allowed them to revert the 1 second delay as well.
Another offender is Reverse Archon. That thing has to go, the sooner the better. But their solution will be something like making Swami a Shock Pulse item…
