I think discharge missille's Area attaks for sentiels doesnt work.
Skill increase range, stops movement, but do not apply area attack
I made several tests that confirm that.
t1 20 sentiels vs 20 tec flaks sentiels 2 upgrades on armor and 2 on missille , tec 2 upgrades on armor and 2 on flak guns
bouth fleets were "on" each other, no discharged misille sill. 11 sentiels survived, all flaks were destroyed
t2: same setup, but sentiels got discharge missille skill on
Again bouth fleets were on each other, in range of skill ( checked several sentiels every had few flaks in range of area dmg) and again 11 sentiels survived.
Tests were repeated,
in tests we didnt focus fire on bouth sides.
And it looks like sentiels main weepon is screwed
We also did some tests with lrms and hoshiko, but results were uneven due to repair and antimatter level
