well the best monsters to kill are the ones that dont poison, mp drain, or stun. i am lvl 82 now and i found the best places for you higher level botters. here it is.
lvl 70-75
Magnificent Ridge
kill those bandit leaders, if you go west of ridge, there will be scattered clots of them. set your bot area to small and just kill the 2-3 that are there, wait till respawn.
North of lost village
theres a few styxwolves there, like 2 only, however you will not aggro. again set bot area to small and enable there. i never wake up dead.
lvl75-80
Bladewolvens, they are outside of dream searching port, they are abundent and some of them scattered, look there.
lvl 80-86
Snakes south of 1k stream. the are lvl 84 however they are loosely packed, they hit low and are physical. if you are playing with a WB/WR its the best to bot there.
other good spots.
burning land offer alot of spot with melee monsters, most monster pass lvl 80 is melee.
spiders in expeditionary camp is also good to kill, dont go to to the zhen spot, insted go north, there will be tiny spawns of them. they are good to kill and gives around 600-700 exp per kill.
lastly tips on botting:
always bot while the GMs are offline, normally 6am-12pm CST. no one can report bot then.
however if you wanna bot past that, its strongly recommended that you watch your screen, or join a party.
oh i forgot low levels.
DWAN is an excellent place to bot, once you join a party, bot away. check every hour, make sure you have miji on. you come back repot. safe and easy. :P
happy botting
