Encounter Design needs to be overhauled at a fundamental level

[Shurrikhan]

At the very least, tanks should get way more damage imo to the point that you will consider using Cure I. Alternating between Cure II and Cure I for MP management sounds way more interesting than spamming Glare (same goes for equivalent abilities of the other healers).

Unless the damage rates are minor and target-specific enough to really allow for Cure I, this will just as likely force occasional complete downtime (e.g. no Glare-spam) to conserve mana for Cure II when such is actually necessary, especially for the less confident players.
