It appears that Bungie is listening to the community by possibly removing Iron Domination from the pool of bounties on offer for Clash. The first people to point this out were some users on Reddit. User jdcockrill points out that while he missed the first day of Iron Banner, he hasn’t yet seen Iron Domination come up as a bounty.
Getting this daily is viewed as rather difficult since players need to get an individual score of at least 2500 in order to earn it. The user also pointed out that getting that kind of score means you basically have to carry you team to victory since the top score of Clash is just 10,000. While it’s not impossible it certainly isn’t something that anyone but the best Destiny players are going to be able to master.
After the initial post was put up, there was some rather extensive discussion as to whether or not the Iron Domination had indeed been removed from Clash or whether it’s still in there and just not as much of a sore thumb as it was. Bungie has not shed light on this just yet, so for now, the fact that it’s hard to find and not standing out appears to mean it has indeed been removed.
