I got feedback from Support advising that running DR: Regeneration alongside a sub with a strong drive to action could result in them kind of cancelling each other out due to DR: Regeneration’s parasympathetic nervous system activation scripting.
Which was indeed my personal experience when running it alongside a custom with Hero TLTB - Earth & Spartan: The Beast Unleashed.
Prior to running DR: Regeneration, I was getting strong results from that custom, but as soon as I added DR: Regeneration to my stack, the results dried up (and stayed dried up for the next several months).
I appreciate that this is just my own result, with various unique factors, and that we all respond differently of course 
But according to the posts from @SaintSovereign here so far, it seems like Summertime is also based heavily on this same kind of nervous system regulation.
But it sounds like you’re saying that this sub CAN run alongside a heavily action-focused sub, such as C&C or (in my case) Emperor: Executive, without affecting the action-drive and results?
Is this definitely the case, and if so, may I ask what then has been changed in the way it works with action/drive titles, compared with DR: Regeneration?
I really want to run Summertime (it sounds amazing!) but I’m also running an EE & RICH custom right now (both the latest versions) and I’m really worried about somehow cancelling out the drive and results from EE especially if I do run Summertime alongside it?
Hope you can advise, and thank you!
