Which class for Dungeon Crawl focus?

[Legidias]

I have played extensive bard. Yes, you can do dungeons on bard. No, it is not very effective or efficient.

Besides the above kiting methods, bards (sub 50 dungeons) can so just dot snare a mob up a corridor, mez it for a split sec in between dot and get past mob, and then dot snare down corridor again. Rinse and repeat. The corridor can be as short as you want as long as it gives you a little time to run past mob back and forth on mez (note that mez length will only be like 1-2 seconds due to dot).

Charm kiting is viable, but can take a long time depending. Sometimes mobs can be found in pairs, but much more often in groups of 3+. Of course, ideally you could lull one and kill the other 2, but then that leaves the third one.

You can either kill the first two, and then corridor kite the third, or do a rotating charm kite (in case lull fails or you want to kill all 3 together in cases where you dont have room to corridor kite). To rotate charm, you basically mez one, and charm other mob + dot final one. When charm breaks, you will want to charm the dott'd mob, mez your previous charm pet and sic your new pet on the previously mezzed mob and dot that one. Rinse and repeat.

You can do up to your mez limit with this, but danger grows if you get stunned and miss a mez / charm. I used to do this in LGuk camping DE mask / belt for money. You can corridor kite most of the way down there with a little bit of charm kiting. Then doing the room itself you have to basically kill all 3 with charm since you dont have room to dot kite.
