We changed a topic here, so I would like to go back to class system and this certain skill
War Cry
I have been playing and thought again about my favorite heavy class…
With the War Cry, I must say, that honestly, I like the effect, but looks OP, and push the heavy class to its weird role
And another point - for me, this is completely nonsense - a human soldier can paralyze “biological horrors” by screaming. Yes, it is just a game, but Phoenix Point is focusing to the atmosphere and lore.
I can imagine some kind of unique weapon (or grenade) with this unique effect, based on electro-magnetic shock wave or something like this, there can be nice story about it
You must get special stuff from special mission (hard difficulty), do a special research, and than You get this unique weapon as well-earned reward
I was asking myself - why this is in the form of character skill ? 
EDIT:
You can also warcry enemy turrets preventing them from shooting.
