I don't care about Batarian Sentinels. Already got one in the Victory Pack.
Today I managed to get two Resurgence Packs. No Batarian Soldier.
Now... I've been counting the Premium Spectre Packs and Resurgence Packs I've been buying since the DLC came out; they've amounted to a total of 25 (11 PSPs, 14 RPs) plus the Victory Pack.
Now, based purely on numbers, a Premium Spectre Pack, which guarantees two Rares at the very least, has a 2/28 or 1/14 chance of getting a Batarian Soldier. Both the Resurgence Pack (2 Rares, one is guaranteed to be Resurgence Gold content) and the Victory Pack (one Resurgence weapon/character) both have a 1/10 chance to grant the Batarian Soldier.
By the numbers, I should have acquired at least one Batarian Soldier at this point, as I have a 15/10 likelihood at the very least to have found one in a Victory Pack/Resurgence Pack. However, while I've found multiples of other characters (my GI is maxed out) and weapons (I have a Striker VIII and GPSMG VI), I have had absolutely zero luck getting a Batarian Soldier.
To not have a Batarian Soldier despite those odds is literally bending plausibility by this point.
And, to make it worse, one of the people I played with in a great Gold match was using a Batarian Soldier. That same person managed to unquestionably top the scoreboard.
