I did a lot of testing on my pug, I tested all 4 attacks on mobs solo, and the conclusion always came up the same for manual attacks, heavy strike, flurry, flurry, flurry, flurry, flurry, victimize or 3x1000tp attacks
the problem with other attacks is the trade off, a little more tp or evasion and defense vs much faster kills
keep in mind my evasion setup with a regular weapon is 198, defense gear showed to be decent for mobs with high accuracy (which is nearly all since we are screwed on dex for now

mashing 1 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 3 4 5
that's the core of pug right now, sad but true
