I'd like to see Sage get something similar to Black Mage's old Thundercloud procs to help pad out the Addersting system. In addition to a GCD shield breaking, each tick of a DoT set by a Sage has a 5-10% chance to give you a single use of Addersting. They could adjust the length that E.Dosis and Dysk (say 21 seconds?) to help balance it out a bit more and set Sage apart from the other healers. Heck, if they wanna take it a step further, they could have Addersting stacks gained from GCD shielding be a slight damage gain while those from procs deal damage similarly to current sting/toxicon. That way good usage and timing of GCD shields feels super rewarding
