On the other hand, if you happen to have a bigger differential in iLevels (for example, you have 4-piece T14, but you're using 2 RF T14 pieces with 483 iLevel in those slots, and have T15 iLevel 522 items for those slots), then use the 2 T15 pieces instead, independent of fight type.
On another, albeit similar, topic regarding PoM; can anyone tell me if there's any practical difference of using the PoM Glyph or not when you have T15 2-piece bonus?
