I still find it amusing how many people don't grasp simple concepts.

1) Summoner has higher utility and DPS than Red Mage, if physick was made stronger (even if it wasn't as strong as vercure) this would make them lower their existing utility and dps.
2). Summoner and Scholar branch off from arcanist. Physick is an arcanist move that both jobs share. It can easily be moved or removed by the player/players that consider it useless without needing any help from the powers that be.
3). Any time wasted on trying to fix it so people don't have to do the "dirty work" is time and resources that could be better spent on something else... don't we "waste resources" enough we really don't need to add a silly request like this to the table.
4). As anyone who hard core raids will tell you, makinig Physick stronger will just help skew the meta even further... we want less of that, not more.
