Flashpoint loot drop systems

After running a few flashpoints on my two characters, I notice that despite a few exceptions, the majority of the FP item drops seems to lean toward usability by the characters I am running.

ex: Sith Assassin with Agent tends to drop all willpower items or all cunning items. If running a bounty hunter, more aim items drop.

Anyone have any idea when this is decided? Is it triggered upon opening chest, or upon attacking the enemy, or even upon entering the zone?

The reason I ask is because I'm after certain pieces of armor for my BH, that are actually Warrior pieces (I just want to swap out the mods) I actually don't play a warrior right now, so I am wondering how I can influence the drop of warrior armor.

So I'm wondering if I made a warrior
Ran the FP with my other two characters
defeat a boss
log out one character, log in the warrior and enter FP,
then open the chest, what will happen?

if no one knows ill probably test myself and let you know the results, but I just wanted to know if anyone had done any similar experimenting first.

I have found this to be true regarding the majority of the loot I encounter, irrespective of flashpoint or general questing; running my Juggernaut solo the majority of the drops I see lean towards my main or my companion.

I believe it is working as intended to provide a better experience for players; I hated WoW for that very reason that the majority of the BOE epic drops I came across never were usable by my character.

I'm not so sure... I ran Esseles last night with my Consular duo and their companions (nobody else in group). Every loot drop except from the Sith was a Trooper/Smuggler item. The Sith dropped a light saber, but it seems to be 50% saber, 50% blaster from what I've seen (I've seen groups of 4 jedi get a blaster drop).

So at least at the lowest level flashpoint, it seems to not matter who is in the group.

The problem with these is that the majority of the ones I've seen are BOP, so it's just vendor fodder. I wish I could at least send them to an alt :)

IMO, it's the limited types of stat combos on gear, very easy to see gear drops streak favor your group composition.

I did a FP athis with 3 warriors and a inquisitor and almost everything that dropped was agent related (sniper rifle, med gloves w/cun.)
