Makes sense... Obviously most reasonable way to fight such dt is with lightning based spells. Hellfire stream is forgivable only until 5x torment is stacked, after that upkeep them with shock only. WoF should be still your priority spell unless it's feated for incinirate, in that case forget it. Demo got good ccs, while dt is easy to kite with his range. Save anti cc for long stun and save one of yours ccs for interrupting his fear. This is basic tactic in a nutshell. Also dont go nuking with his seal of yog drain (lasts 15sec).
