Summoner dumbfire pet durations are all 6 seconds. Old wiki pages match with my memory of these spells lasting 45s (Blighted Horde / Aqueous Swarm) and 30 sec (Awaken Grave / Roaring Flames). Were these changed majorly at some point due to live functionality? The swarm pets are particularly useless with such a short duration. Photo of Lich just to make people aware...
Confirmed that the dumbfires are pointless on TLE/beta. You're basically spending 200 power to deal 30% damage of a single auto attack. These short durations completely break these spells for both necros and conjs (Awaken Grave / Roaring Flames) & (Blighted Horde & Aqueous Swarm)
Dumbfires are not really worth casting on single target fights until EoF. Awaken Grave has some use for AoE pulls.
Reducing the duration from 45 seconds to 6 will not be fixed by AAs The damage is very low, it's not like they hit x4 harder to make up for the smaller duration. The pets hit for like... 60 damage.. twice.. and then despawn lol. Always, I give up on necro for now. Too broken.
