If you care about your encumbrance, and most do, then the requirements do not work with the how most play the game. For example, Tier 4, you need 4 FP parts and r60 weapon. To be fair the encumbrance is around six, I prefer to wear leather boots to stay near zero, so more than I want, but manageable. The step up to Tier 5 and 6 is where it stops being practicable unless you play destroyer. Tier 5 is five Infernal parts (no Infernal legs available, so even worse) plus an R60, tier 6 is an R70 weapon, but now I am playing at 40+ encumbrance, if that worked for a mage, we would all be doing it already. I can see it is risk versus reward but can't you just scale it up please, 4 Infernal, though we would need legs added to the game plus the R60 / R70 ? As it stand to get the highest rewards, not only are you risking a lot of gear but nerfing yourself as the extra protections do not scale with the damage lost.
