Yes and removing trip wire flares was also a nerf but the rest of changes where buffs. Overall Shock where not nerfed and claiming that they where is simply misleading.
Lets fact check a bit, shall we?
Patch notes:
Shock Troops
Shock Troops have been adjusted to have lower bleed effects on a player’s manpower due to their short-range while their grenade has been improved to assist with flanks and dislodging team weapons.
Reinforcement time from 6.5 to 5.5 (buff)
Reinforcement cost from 33 to 31 (buff)
Yes, because they were unbearable to reinforce even if you had just 1. They ARE incapable of inflicting more bleed then they receive, therefore they are inefficient.
That problem was slightly diminished, not solved by reinforce cost.
Trip-Wire Flares removed (nerf)
Poor shocks, the ONLY soviet unit with that ability had it removed, how will we ever go over it?
The ability should have NEVER been there in the first place, there should be something useful and meaningful, designed for the unit specifically, not a general "slap it on everything with 2 legs and no setup time" thing that no one sane even used on them.
Veterancy 1 now reduces Smoke Grenade cost from 15 to 10 (buff)
Completely irrelevant due to not being able to throw 2 nades.
Veterancy 2 -40% Smoke cooldown moved to veterancy 1 (buff)
Same as above.
Grenade Far AOE from 0.15 to 0.5 (buff)
Normalization, it was weakest nade in game and it isn't any stronger then any other nade, still is weaker then plenty of them.
Grenades now share a cooldown (nerf)
A unit killing one as its only gimmick was stripped from it.
Grenade damage type from small explosive to big explosive; can now damage ambient buildings (buff)
Again, normalization and hardly shocks specific change, ALL nades were changed this way or already could do it for a long time.
Note that the grenade does more than 3 times damage Far which is major buff and the reason why it share CD with smoke grenade.
Instead of using "now 3 times more!" advertisement misleading slang, how about you use actual damage values compared to guards nade, rifles nade, rifle nade and bundle nade?
Because "3 times more" out of low value to bring it up to standard isn't making them any stronger, its just a nade aoe normalization for THE weakest nade in game.
