The current Transmuter is by far the least dependent on the Rock Heart of the three beta incarnations, probably because his class ability is basically two built-in Rock Hearts. A third is nice but also redundant. It's no longer a matter of extra MP regeneration with the Rock Heart or no MP regeneration without, because you'll now regenerate MP either way - all the Rock Heart does is give more MP with fewer walls consumed. Since most dungeons have many more walls than you'll actually need, it's not that big of a boost. Most of the time you'd probably be better off with the Trisword.
Also keep in mind that the current Transmuter regenerates +4 MP every time a wall is destroyed, regardless of how it's destroyed. PISORF into a wall costs a net 0 MP (+2 MP with the Rock Heart, but if PISORF is the only glyph you're using the extra regen is nowhere near as useful as extra base damage would be, especially since Transmuters don't get much benefit from Strength Potion abuse) and adding knockback to your attack is like having a +4 MP lifesteal.
Even the low MP cap on the current Transmuter is mostly irrelevant; all it does is make it hard to cast the expensive spells (WEYTWUT, APHEELSIK, and CYDSTEPP) but those have very limited utility for a Transmuter. For everything else, you have nearly limitless regeneration mid-fight, so the only times you'd benefit from a higher max MP is on level up or when quaffing a mana potion (and against Namtar, who can be unbeatable if you're relying exclusively on PISORF and haven't increased your max before you go down).
