AoE looting is an interesting feature, I could definitely see people in the mid-late game wanting it for certain bosses. Within some instances, boss loot will stay on the ground for a long time and build up as you farm the boss, and it can take a surprising amount of time to pick up all up. Vorkath, Muspah, Grotesque Guardians, Kraken, probably more all leave a ton of loot cluttering up the floor
You can also set a threshold for item value too. So if you don't want to collect small drops under 1k or 100gp, area loot will still show them but only pick up the more expensive items when you press 'loot all'.
So far I like how smooth it is to level up skills in rs3 compared to old school. In old school I feel like it shouldn’t take u 10 hits to kill a chicken or cow early on
