Monk can do it as well with Torment's Reach. And if you have high INT the cone size is huge.
The cone of Torment's Reach is independent from weapon damage and has its own base damage (crush), but it works with all spell chances (x% to trigger spell on hit or crit) and also prone or stun on crit.
A great weapon combo for monks is Starcaller + Badgradr's Barricade. Since the low base damage of both doesn't matter for Torment's Reach but the high speed is beneficial, you can proc the stun and the Thrust of TV even more often, dealing tons of AoE crush damage in the process. In general bashing shields make sense with a monk with Torment's Reach - because of its unique properties. Low base damage doesn't matter as I said and bash gets +1 ACC per level.
Of course a second weapon would cause more damage, but the combo of higher survivability with nearly the same damage output is great.
A monk with shield can also get away with thinner armor, making up for the speed loss when auto-attacking a bit.
Thanks for the info; I did not realize Monks have melee AoEs as well.
But I am not sure I'd like to play Monk. To begin with, I am not in favor of Monks in most RPGs, as they usually function best without armor and attacking unarmed - and this is very immersion-breaking and seems "gimmicky." Moreover, in this game, they even require to get hurt first in order to deal good damage - which seems to require even more micro-management!
