My anecdotal evidence proves otherwise.

In the half second (seems longer TBH) after you cast Regen if the tank aggros the mobs, they WILL go after me the healer.

Have had regen on the tank saw them charge in, and still got aggro before. There's something funky with the system (like all systems in FFXIV).
