You won't fucking believe what I discovered. So all default terminators in 3.0 have 3 attacks.
Tartaros/Cata/Command guys 3 attacks
Cenobium 3
CrimsonPals 3
Gorgons 3
Varagyr 3
Ebon Keshig 3 (yeah like Justaerins and Dethshroud they used to have 3 default attacks in 2.0)
Firedrakes 2 but their default hammers give +1 A
Lernaean 3
Dethshroud 3
Grave Wardens 3
Red Butchers 2 but their Axes give them +1 A
Contekar 3
Sekhmet 3
Justaerins have 4 (they used to have 3 by default in 2.0 so i guess this is their thing as ultra powerful guys)

Only Phoenix Termies have 2 attacks. So I wondered, but why? They literally have AP3 weapons; they easily die to many other ranged or melee units, and they don't really have any ranged firepower. They only have their partial +1 WS ability that isn't really that good without Shriekers anymore. WAIT, THEY JUST FUCKING REMOVED ONE ATTACK BECAUSE THEY NOW HAVE THAT ABILITY WITHOUT ATTACK PENALTY. HOLY FUCK. It's shit like this that makes me lose faith in GW game designers. It was a niche thing that was used in conjunction with -1 to hit from shriekers and another rule that counted a draw as a victory. It was a fluffy and interesting EC mechanic. Now they just removed -1 to hit from shriekers and removed Living Icons' ability to simplify the game, and then they "OPTIMIZED" the -1 attack from the 2.0 Skill Unmatched ability into the default profile. It's insane how stupid some of their decisions are.
