As it stands, Risla's Freedom was the only spell that clerics had that were 'cleric-like'. Clerics have nothing that identify them as a guild, they are simply a compilation of relatively crappy spells from other guilds, that, when you reach a certain level are actually quite decent.

Risla's freedom is a spell that everyone knows was way too powerful, but if everlastings are anything like what was in Mog's castle before, I think they're also very powerful. Risla's freedom is a spell that could have been reworked in such a way as to not affect players first off, and secondly, so that it wouldn't instantly kill anything. It could sever limbs, cause damage over time, it could be a slightly stronger harm spell for undead only. I could think of many ideas for it, but removing it completely was a band-aid solution.

If evers are put back in, I don't see why clerics shouldn't get something that they can identify with, and also something to allow them a chance agains evers.
