So I got the LFR Galakras helm(the one with Haste/Mastery), and the Flex Crit/Mastery gloves off Flex trash(Crit/Mastery). Would it be worth it to equip these two and break my 4pc? My T15 gloves and helm are ilvl 530 fully upgraded. I gain a ton of Crit and Mastery swapping, but I'm so used to 4 pc and the burst it gives now that I'm hesitant to break it.
