I anticipation I would account out all the abilities that acquire a 1m+/hr (or abutting to) xp bulk as they all charge to be avant-garde too.
# Combats - I would account all the accessible creatures that you can get 1m xp/hr, but I would run out of acceptable characters in this post, it caps out about 2-2.2m xp/hr at burst worlds tryharding.
# Prayer - Scatterbury with Dragon Bones/Infernal Ashes is about 1.2-1.3m xp/hr.
# Herblore - Overloads.
# Smithing - I haven't done abundant training as I was 200m column rework, but i acquire ancient 5 to burying is over 1m xp/hr.

# Crafting - Cutting Dstones is hardly over 1m xp/hr.
# Firemaking - Angle can, able-bodied over 1m xp/hr (can get up to 2m xp/hr), and even on the poor ancillary coiled roots get about 900k xp/hr.
# Fletching - Broads are 900k xp/hr and added big-ticket methods can be done to get aloft 1m xp/hr.
# Apache - Absent Grove Creatures and Gemstone Dragons both hit able-bodied over 1m xp/hr and with the 120 apache advantage you can about alone do them.

# Hunter - Aforementioned.
# Summoning - 20m xp/hr anyone (~12m xp/hr off dxp).

That's 20 of the 27 abilities with animate reasonable training methods that are abutting to 1m xp/hr, while 2 others (Agility and Invention) are about complete xp/hr.
That leaves alone RC, Div, Mining, Fishing and WC as the alone abilities that do not charge to be modernized.
