Also, 2nded that the Warped Swarmer nerf was pretty Brutal (pun intended).
+1 damage only on the turn a swarmer has died is ridiculously weak compared to other swarmer (and non-insect) cards. IMO it puts it almost on the same scale as the flame dawn commando (cost 1). 4 resources and 1 card slot gives you a 9/9 insectiod and +2/+2 to every other swarmer in the case of the Brutal Swarmer and 2 Warped Swarmers take up 2 card slots in order to give you 2 5/5 insectoids and SOMETIMES +2 to damage (not health) when and only when the insectoid died due to combat damage.
PS. kudos for listening to the Brood Queen idea and implementing it
PPS. suggestions for improving: Brood Queen's 2nd effect is only Insectoid Creatures may be used in the deck. That is, whatever factions are in the other command slot determines cards available and then non-insectoid cards are blacklisted.
My suggestion for Warped Swarmer is 'when swarmer dies to a non-sacrifice effect all opposing creatures take 1 damage'. Rationale: the biggest abuse seemed to be using sacrifice abilities to trigger aoe damage on the enemy at-will (personally guilty).
