We already have RSST/RSSS for that; it doesn't make sense for PSTE to just turn into any element matching it's ctype; it's only meant to turn into rock-based elements, life BRCK or CNCT. And before you bring up the fact that LAVA and ICE/SNOW freeze and melt into any element to which you set the ctype, nobody freezes or melts them into anything other than the elements into which they naturally freeze or melt, or SING in the case of SNOW(SING).
Exactly; it doesn't make sense for PSTE to turn into SAND or any element other than BRCK, PSTS, or CNCT. Here's one upvote for understanding what I'm getting at. 1+
PSTE is only meant to turn into rock-based elements like BRCK or, if my suggested feature is added, CNCT. It doesn't make sense for PSTE to turn into anything else. We already have RSST and RSSS for this. We're getting of topic here, this thread is to discuss the PSTE turning into CNCT, not to discuss PSTE turning into just any element.
