Thought post, will turn into a plan fragment when I'm off work.
SUMMONING: The new summoners are not really valuable as summoners yet, they won't have many contracts. This makes them more of a liability than an asset for front-lines.
Proposals:
1: Ruri can send an envoy to Kei, Asuma can send an envoy to Kei, Hazou can already communicate with her instantly etc. Use the summon network for logistics/spying instead, as information transfer is instant.
2: Summoners that meet up in the 7th path and human path can set ambushes by instantly appearing from the 7th path at the same time.
3: New Summoners are a liability on the front lines. Turn this into an advantage. We'd make great bait.
MISC.: Asuma should get a monkey to Toad ASAP so Noburi can keep him topped up at all times. Orochimaru and Tsunade too though they will take longer.
GOKETSU ASSIGNMENT:
1: Mari would better explain where she's best suited, but she's one of the best support fighters Leaf has. Internal reasoning: TLitF + SC = 50 dead ninja.
2: Noburi should be in the hospital, transferring chakra from injured nin to Summoners via 7th path when he's not helping patients. Otherwise, he'll probably need a dedicated guard at the battlefront or stay reverse summoned until needed, Asuma could retrieve him.
3: Hazou and Kei are likely better for logistics and strategy, in addition to aforementioned Summoning tactics.
4: Kagome is a security expert, best fit for defending outposts or Leaf.
5: the rest of Gokestu... are probably best for the front lines...
DEFENSE:
1: 5SB nets prevent kinetic bombardment, but not firebombing. Keep a Hyuuga above Leaf at all times.
2: Chakdars are an advantage they don't know about. They aren't much but they're an edge, gives us some notification before a strike.
