Yes, this was changed if I recall due to the fact people can now craft greater restoration potions as well as Heal potions. they spell Heal was lowered to 10HP/lvl max of 150. otherwise people would just keep chugging them in battle completely removing the need for any healer at all, and would make PVP annoying because it's just chug a heal or greater rest and BOOM full HP... at least now you have a better chance to kill em.
