Subclass and general build help

[Mr.Hero17]

New poster here, figured it be best to make a separate post for getting some help with how to spec my party.

So here's my current party
[spoiler]Class: Monk Lvl35 170HP 171TP
Skills:
Healing 5
Full Heal 1
Line Heal 5
Party Heal 1
Refresh 4
Resurrect 4
Fire Walk 3
Form Qi 7
Fist Mastery 3
Blood Return 1
Unbind 2
Kioken 1
Subed Prince
Royal Veil 2
Nobility Proof 1
Attack order 1
My Thoughts: I'm pretty happy with this guy since the monk skills are great for healing and the prince subspec will give him buffs and free passive healing

Class Hoplite Lvl 36 286HP 97TP
Skills:
Guardian 5
Shield Mastery 5
Recuperate 5
Parry 5
Magic Parry 2
Line Guard 4
Antifire 1
Shrug Off 3
Provoke 6
HP Up 1
My Thoughts:From what I've read Hoplites are pretty solid without a subspec so I haven't known which one to actually give him. Also as a tank he's pretty kickass, might need better skills for covering others but he's pretty much always the last one to die when things go bad.

Class: Ninja Lvl35 162HP 99TP
Skills:
Keburi no Sue 5
Knife Mastery 5
Senpuku 5
Kagenui 3
Izuna 5
Fukubari 3
Suikyou 1
Makibishi 5
Kagerou 3
Bunshin 1
My Thoughts: I'm conflicted about this guy, for a while he was pretty bad but once I got Keburi no Sue and Izuna up he's pretty awesome for petrifying guys on the first turn of a fight. His actual damage is kind low though and during boss fights he doesn't seem that great.

Class: Zodiac Lvl 35 166HP 226TP
Skills:
Horoscope 5
Ether Mastery 2
Ice Mastery 5
Singularity 5
Etheric Return 3
Ice Star 1
Binary Ice 1
Meteor 3
Etheric Charge 5
Dark Ether 5
TP Up 1
My Thoughts: I'm not sure what's so good about meteor it cost a whole ton of points to get to, is there a stat or something I need to boost to make it awesome? Otherwise I like my zodiac, he can put out good damage.

Class: Arbalist 166HP 69TP
Skills:
Giant Kill 5
Bolt mastery 9
Proper Form 3
Extend 2
Double Action 2
Heavy Shot 5
Front Mortar 4
Strafe 1
Volt Barrage 1
Armor Piercer 4
My Thoughts: He puts out good damage and is generally useful but I feel like his skills are lacking, I don't have anything giving them synergy.

In terms of game progress I've just beat the two lost ones or w/e in BF10.
[/spoiler]

So any suggestions on how to sub or respec people? I also have a glad, buccaneer,princess and wilding in my guild hall who are in their mid 20's due to combat study.
