(I copy and pasted my response to someone else with the same argument here to avoid re-typing it all) But you can run the raid 16 times per character in the same amount of time it'd take to get all 4 IB items. In addition, once people get the hang of it more, you are only spending 1-3 hours per week to get 300+ gear. With IB, you need to spend more than 3 hours at least on your first character in order to get one piece of armor. I did the raid once which took 3 hours and got a 305 ghost, 305 Mark, and a 305 Auto Rifle (the rifle sucked so I infused it). At that rate, I can easily get all of my characters to 300+ way before 4 months (which would be what it'll take to cycle through all the IB armor gear). Also to my knowledge there are no IB ghosts or Artifacts either so really the raid is faster and easier to hit 300+ as it is. While it's not raid gear, the grinding and length of which to complete it is so much longer, it should be at 300. If they had all the armor and weapons available (like the other vendors) then yes, I do agree it'd be way too easy to play IB and rank up. However, since it's a limited one month event (even Trials is more consistent and available to the player being a weekly event) and is super limited when it comes to rewards made available for purchase; I feel it's ridiculous to expect people to spend their marks on something so low. Finally, like it or not, IB is basically made for people who have achieved max level through the end game so in actuality, it's more "end game" than the end game itself.
