To be clear:
Please read carefully. I am referring to the talent trees here, not the GSE macros (of which you can create as many as you like, and if you use them to fill your entire action bar).
In this guide, you’ve tied two different talent tree builds to three GSE macros:
One to SHAT_STAR and the other talent build to DEV_SINGLE & DEV_AOE. If SHAT_STAR is to be used together in alternation with either of the other two macros, your guide logically also refers to a second talent tree, at the same time → not possible.
If it’s really possible to use two saved talent builds (talent trees, NOT the GSE macros) at the same time, please enlighten us.
