[Kara] Attumen always selecting Nightmares HP amount on merge

[balleny]

Current Behaviour

when either attumen or midnight reaches 25%, they merge and get the % hp of midnight

Expected Blizzlike Behaviour

once either of them reaches 25%, they should merge and get the HP of the highest total of either of them

Steps to reproduce the problem

damage only midnight, they will merge into midnights hp

some sources I looked at:

Classic TBC
https://www.youtube.com/watch?v=D8OZU8bg6lk
Midnight initial hp 379.4k
damage to midnight to 25%, spawned hp visible 379165
https://youtu.be/D8OZU8bg6lk?si=dY2sCCbLbLj2NvJX&t=1271

non-archived WCL log https://classic.warcraftlogs.com/reports/k1XYj4gwa8cV3FCm#fight=5&view=replay

Classic TBC
spawns 100% hp
https://youtu.be/kul6efg1hZA?si=N04-yIn3G1E2JeDC&t=150

Tested:

Attunement
1:
Hit midnight to 200k/265k
Attument to 25% hp 25k
result 200k/265k

2:
Hit attumene to 202k/265k
Midnight to 65k
result 202k /265k

3:
Hit attument to 100k
Hit midnight to 65k
result Attumen spawns with low hp 165k/265k

?

they should merge and get the HP of the highest total of either of them

I'm confused by the wording. What is the expected behavior?
Should spawn with remaining midnight hp + attunement hp?
1: 25k+200k= 225k/225k
2: 202K + 65k = 267k/267k
3: 100k+65k = 165k/165k

fix could be changing this

azerothcore-wotlk/src/server/scripts/EasternKingdoms/Karazhan/boss_midnight.cpp

Line 154 in a8b69ed

if (midnight->GetHealth() > me->GetHealth())

to

summon->SetMaxHealth(me->GetHealth() + midnight->GetHealth());
