With the right atma u should be capping 4k-5k with a 2k-2.5k avg and with /THF 7-8k with a 5-6k avg

Also i have done 2k outside of abyssea /SAM so i have no clue how you can only do 1.2k inside.

Anyway as far as Torcleaver goes it's only lacking because it doesn't crit because outside abyssea it's one of the best (top 3 at least only bested by Ukko's and maybe Fudo)
