My wishlist is go back to S1 DF spriest, with a choice node between sear and link, as with all specs less or no 2 talent nodes and fill back up with new talents.
I’ve been also contemplating the purpose that spike could have, I think that having it as an alternative to flay is pretty uninteresting, I would instead prefer if it was like fire mage fire burst, which means it could be used in between other abilities and doesn’t follow standard gcd, but could only be used when it proceed, with a medium proc rate frequency, based on either dot ticks or other ability casts, and generates apparitions.
Also make crit conjure 2 apparitions.
