this below is based on my experiment, please correct me if im wrong
other option is to use a lot of DEX equipments,
my vit is 54 at that moment and im using Dame of Sentitel card (54vit/18 = 3 dex + 3 dex from glittering jacket ) ( must be 90 vit to get 5 dex )
DT is good, i stoppped level my new rebel awhile and farm to get better dex eqs ( currently testing mech )
at lvl 112, my DT can hit 260k thats with full buff
+10 AS end of horizon
tested on dark priest, dark illusion
also having hit rate around 545, makes me able to solo Hazy easily at that lvl
i dont know sometimes i can hit 120+92, not sure how
DT is burst skill, almost no cast for me with hit barrel on
but whatever you do, you never able to spamm it because it has long CD ( 5 secs )
that's why, i went to utilize GS skills, thats including Trigger Happy Shot, Gunslinger Mine, Spread Attack and Full Blast ( even if shotgun is not my build )
because you are rebel, you have better weapons and buff to increase skill modifier.
spread attack damage is increased by hit barrel not altar, weird enough
from like 8k normal, to 15-19k 7x7 aoe and you are able to spam it, but round trip deals higher, deal lots if you have high dex so i recommend gatling type is a must for leveling phase
gunslinger mine, increased by hit barrel
Full Blast is my fav, ive killed FBH with it
while my friend tank him, i spammed that skill from far, it has bonus range from snake eyes passive
the damage is not bad either, 1300% by default and high refined AK death fire will make that skill hurt so bad with platinum altar on
