I have 66,350 points left.

 

Is Jagex going to be releasing any more auras in the future, or should I just use up all of my points now instead of saving them?

 

Right now I'm looking at Aegis and Equilibrium, since I'm not really interested in the adrenaline-related auras. Are either of these worth it in EoC?

Aegis may be worthwhile, as the adrenaline abilities to bolster defense (that boost it to a percentage worth using) are threshold abilities, which means they cannot be activated at the start of combat, and last no more than a few seconds.

The main benefit of Equilibrium is that it reduces overkill. It has diminishing returns depending on the ratio of your damage output and the monster's HP. The update played haywire with both of those, so who knows? I haven't heard of any new research or math regarding its effectiveness in the new system.

 

Regarding the likelihood of new auras: word from Jagex is, if I recall, that they're not sure what to do about the future of the loyalty program. There haven't been new loyalty items since March, where previously they were being rolled out every three months. Bank boosters have been promised for a while, but they have yet to show up. Solomon's store has been stealing the loyalty shop's thunder, basically. In the long-term, I think there's a good chance new auras will be released eventually, but in the short-term, I wouldn't hold my breath. Using your points now is a good strategy because you can take advantage of the discount to get value.
