Savage SCoB difficulty compared to FCoB?

[Brannigan]

iirc, T8 is all about more adds HP and randomized towers (maybe not the order but at least their positions)
...

Savage T8 has a new tower (Max HP Down), randomizes tower positions, spawns up to 5 land mines at a time, has Allagan Field from the start and (in later phases) uses it on 2 people at a time, and has generally increased damage. The adds also insta-kill people if they get too close to the boss. The fight is all about timing bomb tower detonations and protecting people who have allagan field, since it's much more sensitive to damage IIRC. Overall, Savage 8 is the most different fight of all the savages from its normal version. It's also my favorite fight, and is really intense and fun since everyone gets to get involved.

Savage T9 has a very similar first half to its original version, with the exception that Raven's Ascent makes the tank more vulnerable to damage and forces a tank switch. The golem phase drops like 8 meteors at a time, forcing everyone to feed multiples and dealing a lot of damage. Heavensfall phase is much longer, and the pattern in which the thermionic pulses on the ground come is reversed. Additionally, meteors will drop on random targets and deal a bunch of damage if you're too close to the impact site. The last phase pretty much just adds meteors to a few parts (just run them to the wall) and forces tank switches by adding a Ravensbeak onto the end of his Bahamut's Claws. He also uses Super Nova during dive bombs, iirc. I disliked Savage 9 because the first half is very similar to the regular fight, just longer. The last half can wipe your party very fast, so it ends up being a 6 minute slog to wipe in a few seconds over and over.

The basic design philosophy for all the savage second coil fights seemed to be to counter "cheese" strats like superslug, mark moves, single tank 8, four renauds, single tank 9, etc. It's pretty neat.
