The Army are half loyal to Agres and half to Luca, and no Seed and Culgan probably wouldn't side with Agres at that point in the game because they knew that Jowy was coming into the picture and what he was doing. Jowy would most likely join Luca giving the advantages of Leon and Yuber but Sassarai would most likely join Agres as a king of the neighbouring country. Agres would also have more funds for Harmonia.
The White Wolf Army were strong but very limited in numbers, so as for intimidation I doubt it would do too much. Solon Jhee was dead by that point in the game.
HAHAHA, You serrious??? Luca refers to him as old man. Luca has no respect towards noone and Han is loyal and always has been to Agres.What you say holds truth, yet you forgot about one of the most important characters-Han. Han Cunningham would deffinitly be on Luca's side. After all, he saved him and his mother, and then trained him to become a warrior. Han was in fact the only person that Luca respected. And he was Highlend's greatest hero (while Genkaku was still alive), so I think a lot of people would be with Han, and thus with Luca.
Nopes, Agres is wealthy, Luca gets money from daddy.Luca was pretty wealthy...
No way in hell......they weren't ready to organise themselves when they were being attacked let alone organise for an offensive against Highland.I'm sure Dunan would take this time to bolster their forces and regroup, and become united again, then rather attack Highland.
Luca could have killed Agres at any point in the story before Jowy came to the scene. This would mean NO JOWY, NO LEON, NO YUBER, NO LUCIA.
Sassarai would go with Agres (think about it from Harmonia's POV). Solon Jhee, Culgan and Seed are Luca's generals and the way they acted they seem loyal to him until he starts burning stuff like a madman (Solon would probably still be loyal), Rowd is a whimp so I won't even count him, thus leaving Han, Klaus and Kiba with Agres and help from Sasarai.
The REASON he didn't straight out KILL Agres is not so much because of the generals. The MAIN reasons would be the army and the people. The people would hate a tyrant and would easily start rebellions all over Harmonia, and spliting the military force as well as the supplies and then killing half of them off, even if Luca did win he'd have about a 1/3 of his original army. Not a good state to attack Jowstone in. The other reason he didn't kill Agres straight out was because he HAD NO NEED TO!!! He had all the power that he needed. Agres would have easily been fooled by the Unicorn Brigade incident and screaming out for war himself. It was only at a later stage that Jowy came up with the plan that Luca decided to "get rid of the last weight around his neck" aka Agres.
Why destroy a nation when you can control it?!?!
