FYI, I pulled a 320 ghost shell as an IB reward today! That was pretty awesome. So that is 6 light better than anything the hard mode Raid ever deemed to give me.
This method sucks since the purples usually have more/better perks compared to the blues. So, now I'm left with infusing this blue into a good purple and in-turn lose some light levels in the process. Basically devalues one of the rewards people want from IB.
In the end it just means I'll have to do the quests to get the GOOD 310 artifact for my other toons (but I really didn't want too... ugh)
The artifact I got today on my Hunter is actually considerably better than the legendary I got from that quest. It has 8 total more stat points than the legendary and a similar (if not exactly the same) perk. As an added bonus, the rares level up much faster so I was able to max it out really quickly. I don't have a comparable artifact even at lower levels so I'm just going to use that until I get a better one.
On my Titan the 310 one from the quest was pretty bad, too, but the IB one wasn't any better. So there I made use of the 305 artifact I got from Trials and leveled up my 300 artifact (from Eris way back in the day) to 305 and then to 310 using the IB one. So now I have a nice Int/Disc, high-stat artifact at 310. So despite me initially thinking the 310 blue artifacts were useless, I've found a use for both of those so far.
So for the rank 5 packages, you get a 310 ghost in each one. On my first one I also got the IB rocket launcher at 319. But for my second I didn't get anything extra. That was somewhat disappointing. Is the extra drop only a one per account thing, or was it just a totally lucky drop in the first place? I still have one more character to get to rank 5 so I'll see what happens there - I'm expecting to get nothing besides the ghost.
