Fresh 80 ---> Choosing trinkets from website store (Points System)

Hello, hello everyone! I decided to make warlock because it's the last class I don't have yet.
Since I have some points accumulated in my account on the website, I can buy trinkets from the points offer (not coins)
I don't lack money in the game, I have quite a lot of gold. I have already dressed the character for 5.3 GS. I think that trinkets are a very important thing when it comes to choosing equipment, trinkets can make a big difference between the same characters with the same gear score.


Currently I have two specialties: one is Affliction and the other is Demonology.


I use flare as my first choice for both (18 points)
As you know - afliction needs haste. That's why I'm considering either scale of fates or
elemental Focus stone https://wotlk.cavernoftime.com/item=45866 or
Embrace of the Spider http://wotlk.cavernoftime.com/item=39229

Extract of Necromantic Power - Can the process occur on each dot independently? If I play afliction and I have 4 dots on the target, can the process be activated for each of them separately? For example, does it occur once every 45 seconds?And then there has to be a break?

Soon I will have enough of the Triumph emblem to buy a trinket with hit and activated Haste for 20 seconds- Is it worth considering?

*Oh, one important thing - lets assume that I have an 8-11% hit

I would like to ask for advice for a demonology and afli spec.

Thank you all for your advice! PS – Is it worth playing Afli at all if you don't have, for example, 800 minimum ?

Thank you, best regardsp000
