I don’t think power leveling through armor is a good way to level. Primarily you should level up through experience gain. Armor should only partially aid in that leveling experience. It shouldn’t be the primary reason for leveling. It should be, gain experience first, and then find pieces that drop, and add +2 to +20 power levels to your power level. +5 tier 1, +10 tier 2, +15 tier 3, +20 pinnacle. Tier 3 and pinnacles should provide some sort of benefit for using. While sometimes tier 2 and very rarely tier 1 drops with random benefits.
