So i am wondering does shadow warrior is better if the Assassin do not has Enigma and she plays PVM in team with 8 other characters as damage dealer? By.damage dealer i mean she will enter the Tele sorc TP and start lying traps, ect...
As far as i know Shadow master is bad for this certain PVM Scenario since she will cast whatever skill.she wants wich means she will ruin the Assassin powerfull traps by casting her own traps, thats Why Shadow Warrior is better cause she will cast the certain skills that currently the assassin uses on her left/righ skill bar!

Please i am open.for your suggestions and explanations

People usually dislike any Kind of shadow cause they usually stun the wave Monsters at baal or sth like that
if u have a strong merc imo u waste skills i had no Problems at all without a shadow

Well stunning is one of the.things ilike as deffense and preffer the Shadow Warrior to do aswell , cause is really helpfull for earlie ladder when the team characters are weaker
But if i want the warrior to cast Mind Blast aswell i need to put 1 point in it!
Basically instead if wasting that 1 point in Shadow Master i will put it In Mind Blast

warrior casts what you use
master uses various skills, including mind blast

if you're in a full game with other people fighting with you, don't even bother casting either one of them.

master will rarely cast a trap that over rides one of yours.
warrior will always cast a traps the over rides one of yours.
hardly makes a differance tho, its not like she will replace ALL your traps with slightly lower lvl traps, your over all dmg isn't really effected. (i'm guessing)
i think both are only useful as a meat shield.
