don't worry, artillary support is actually useless, you're not missing much, and it cost 6 stars! its a luxury if anything.

Actually do you guys use those orders much at all ?

I tried to use a few of the anti tank or accuracy ones but it seemed to be pretty useless as cost in orders were prohibitive compared to just shooting one more time.

Some orders are needed to complete A rank mission, others just make your life a lot easiers. Some I never ever use.

My most used orders are as follow:

Awaken
Awaken All
Boost Defense
Boost Evasion
Caution
Defense All
Evasion All


I rarely use any of the offensive orders, almost all orders are buffs to keep'm ticking (except for the accuracy boost for when I go sniper happy).

*Random Opinion*

Best Characters for each class:

Lancer:
Hector(best tank killer in game) and Jann or Audrey (for Ulti. armor perma damage boost)

Assualt
Vyse and Rosie: strong stats and best potentials for assault imo.

Engineer
Eh, they're pretty much the same, but I like to use any Darcsens to trigger Rosie's 4th potential.

Sniper
Marina: only sniper with Ult. Accuracy, awesome sauce

Best Scout
Alicia: (godly; resis xfire, double move, full heal and final potential are all amazing)

I use the awaken order the most, caution is also good if a character doesnt have resist crossfire. i'm still wondering how i get awaken all.... i'm on my 2nd play through now

oh and one more thing, i've realised on my 2nd playthrough i'm missing some characters like aika... i have no idea where they have gone to, i didnt lose them in battle, as during the whole game i only lost one useless engineer

They come back, the recurit pool is randomly reset with the 'lost' characters reappearing between chatpers just like your first playthrough. Awaken All is like the second last skill I got, its extremely useful but very circumstancial (there is only a couple of mission where its neccessay).

Hmm i missing most of those orders despite being at chapter 11. When do you get the awaken one ?

All the orders come from the old man in the cemetery and through leveling up classes in barack, the barack orders are fixed (i think) and the old man in the cemetery is random.

Awaken comes from the old man unfortunately.

It seems I missed that one too.....

Just keep going back to the cemetery in your second playthrough, I think a new skill appears every chapter and all orders carry over like everything else.
