Masori armor is one of the heaviest sets in the game, weighing more than double of Armadyl and almost the same as Torva. This added weight is showing a big hindrance at CMs where we don't get fully healed after every boss and stamina management is a big part of the raid.
Armadyl Set Helm:0.5 Top:4 Legs:1
Torva Set Helm:2 Top:9.5 Legs:9
Masori Set Helm:1 Top:8 Legs:7
Masori F Set Helm:1.5 Top:10 Legs:8.5
New Masori Helm:1 Top:5 Legs:1.5
New MasoriF Helm:1.5 Top:5.5 Legs:2
For reference: Walking into a CM with my max duo gear my weigh went from 58kg to 72.
Vespula it went from 48 to 62, forcing an extra sip of stamina if low rolling.
Olm it went from 51 to 65, requiring 1-2 extra sips depending on fight length.
I've been doing 30 CM duos per week consistently for the past 5 months except on the week of ToA release and the only gear Ive changed since then were the ToA items, kills are faster but the stamina drain is insanely higher because of Masori.
PS: Ahrim legs need a weight reduction too!
