or a ww, to kill all the chargers.
hc LLD isn't strictly about lvls, its about items. builds are centered around meta breaking phys dmg items, for the most part. as the goal is to 1 shot the enemy. so tiger strikers, chargers, and ww/zerk barbs are popular. with items like up'd steel driver, clegs sword, hone sundan, insight, etc
people generally stick to dueling a lvl range, rather than a lvl. but dont be fooled, its 90% killing pubs in lvling games. and the dueling is 99% chicken programs saving and exiting, that's a "win". and ear is rare and fulfilling, but rare.
