I know more than a few career summoners are going to say "no, my Astral Conduit, I need it to be good", and I get it. It's a really strong job ability. Too strong. So much so that measures are being taken to reduce its effectiveness, which instead reduce the effectiveness of the entire job. That has to stop.
There's already content where you can't use Apogee, have to worry about your blood pact delay, and can't take a second summoner in no matter how useful it would be, because that's the quick fix for making Astral Conduit less overpowered.
While I don't think this is necessarily the best replacement, I don't want to come here without any ideas for what the new SP2 could look like, so I'd like to offer this and hope someone replies with something better:
Synchronicity
Duration: 180 seconds
While under the effects of this job ability, summoners gain Avatar's Favor +5 (as per Caller's/Beckoner's Horn, and cumulative with that piece of gear), Avatar's Favor is activated if not already in effect and its "warmup phase" is bypassed, and avatars receive Regain +200.
This would indirectly reduce blood pact delay, but not to zero, amp up whatever passive benefit the avatar of choice may have, and slightly improve healing and damage potential. It wouldn't be nearly as potent as Astral Conduit, but this may be offset by increasing its duration to be in line with Astral Flow.
Anyone in here feel like they can do better? Jump in with your ideas, let's give whoever's reading this a few different starting points to choose from, and see if we can't get summoner saved from this weird "too good to be okay" place it's in.
