[@Raijinslayer] Combat wise, the first thing that springs to mind is Violetta's semblance - given the three-second charge time and Daedalus' defensive nature, as long as Daedalus gives Violetta some cover for a few moments she can flank enemies without too much trouble.

Second, Ignatius' abilities means with a bit of focus he can funnel enemies into a small area so that Layla can take out huge groups at once - especially while using Overlode.

Layla and Daedalus seem to struggle at long or even mid ranged combat as opposed to Ignatius or to a greater extent Violetta, so it will be up to you two to pick off enemies at range (Daedalus' crossbow rarely fires lethal rounds so while he can incapacitate at range he may not be able to eliminate targets entirely).

Ignatius' fighting style, abilities and even personality make him ideal for both distractions out of combat and to confuse enemies in combat.

I have a few more things on combat and personalities, but I'll update it in a few hours when I get off work. So far I'm loving the team composition though!

[b]EDIT:[/b] Okay, I'm back - on to part 2! Defensive wise, we have two people who are rather physically strong and can take a hit against two 'glass cannons' essentially, so if we need to split into pairs for defense I'd suggest Daedalus or Layla with Ignatius or Violetta.

Combo moves could include (names are just placeholders):

[list]
[*] Fire Punch (Daedalus & Ignatius - Heats Daedalus' gauntlets red-hot to deliver a fiery blow) 
[*] Whirlwind (Ignatius and Layla - Layla fires her blunderbuss into a swirling tornado of fire which is then launched at an enemy)
[*] Gravcharge (Daedalus and Violetta - Violetta fires a gravity slug and Daedalus uses the effect to charge into an enemy at high speed)
[*] Tracer (Ignatius and Violetta - Violetta's railgun is fired through a long and narrow cone of fire, superheating it before impact)
[*] Heavy Rain (Daedalus & Layla - Daedalus throws Layla high into the air, who uses her blunderbuss to fire down upon a large group of targets)
[*] Shard Blast (Layla & Violetta - Violetta fires a slug which Layla shoots using her pistol, causing both projectiles to explode in mid-air and rain down dust-infused shrapnel)[/list]

Personality-wise, I feel that Ignatius and Violetta would get on quite well despite their polar opposite in personalities (which I think is a good thing).

Both having ties to the White Fang and growing up in Vacuo, Ignatius and Daedalus would have a fair bit in common, plus the showmanship of each (I can see them trying to one-up each other constantly :P) - Although it seems Daedalus is too quick to trust, while Ignatius isn't as easy around people.

Layla's skills in Engineering would have Daedalus confused yet absolutely fascinated, and as the two who are described as easy going and down to earth I think they're probably going to be the go-to pair for conflict resolution.

I think Layla's temperament might rub Violetta up the wrong way a fair bit (think Weiss and Ruby) but the pair would still be able to put aside their differences and be friends.

That's all I have for now; tell me what you guys reckon! [@Aquaknight] [@Rekaigan]
