Yes. 0.32% more burn or 0.32% less time, maybe. So if a fight takes 32 minutes before it will now take 31 minutes and 50 seconds. Win! If the whole thread is consulted, the situation is where you trade off some HEM/AC for that 0.32%. That is by upgrading those chase items with Tier 2 Group gear. Never mind raid drops. That is by going off that there is a theoretical direct relationship AKA linear proportion of Luck to benefits as you increase the luck stat. So, basically you could upgrade a chaser with what is probably going to be the near future's rot loot. Now, perhaps a raid item in the future could update the chasers but for now the rub is the dev's were leaning on not making those chase items obsolete so quickly or easily. tl;dr: Does it really matter?
