Honestly after refreshing myself on the other Jade Phoenix configs I'm settling even more firmly on the Executioner comparison, and none of them particularly resemble any Summoner configs popular enough for me to know offhand. The Prime, B, D, and E all have fairly deep similarity to the Executioner Prime
Assault
Faster/more maneuverable than average
2x big energy 1x big ballistic (the B flips this but is still close)
The biggest difference is that on the JP the extra maneuverability is integral and efficient and more than the sum of its parts, where the Executioner ends up so expensive and less than the sum of its parts.
And then you have the A, one of the most disgusting dueling mechs ever devised, and the C, which is just raw efficient mid and close range damage the likes of which cannot be escaped.
Hard to articulate how good the JP is.
