P2W GB12 average 27 secs
So for the 3 others out there with Manannan and Lucifer, I started running this team which is very safe and doesn't require G3 runes. Only issue occurs if you fail to get Def Break on your first two team ups. Even then, the team manages to pull through most of the time in around 40 secs.
Also, yes, I do know Manannan needs 1 more CR. Just need the right Gem for it.
