I find this topic such an annoying one, specially when i suspect most people don’ even know the value of each individual talent or seems to hate when they buff some talent they don’t like because “now you need to pick it”.
Now, let me being frank, Demonology have more or less 52 total talent points to be placed in it’s spec tree, but you only have 30 talent points avaliable.
There will be always “Dead talents” who are not picked, because you simply need to make choices of what to pick and what not to pick.
Be it because you don’t enjoy it or it don’t give enough value at something or its just a worse version of something else you already have.
Yes, some are very, very, very poor value like is the case of Stolen Power and those need to be changed, others are generally disliked like it’s the case of Doom and they need to be changed, some have a lot of value but in something that demonology already have enough like bloodbound imps and then you have things like Pact of Imp Mother who is just slightly worse than talents you use point 29 and point 30 with.
but you will always have talents you don’t pick, it’s basic math, you can’t fill 52 “talent slots” with only 30 points.
Buff Pact of Imp Mother from 5/10% to 8/15% who is both single target and aoe? ok, remove 1/2 points from the current build, place at it, and now those 1/2 removed talents are dead talents.
Buff Hounds of War from 3/5% to 4/8% and while its still a RNG mess, it becomes one of the strongest talents in the tree due to all the nuts synergy with dreadstalkers, and the 2 points removed to accomodate it are now dead talents.
Buff Imp Gang Boss, who is already one of the most popular talents in m+, used in all the builds saved at https://mplus.subcreation.net/demonology-warlock.html and now you not only NEVER pick fel covenant/sacrificed souls (making 2 more dead talents) but you now also always pick Imp Gang Boss for pure single target encounters.
