Im not native english speaker but this is very challenging to read.
I think you pro SU player and could me told in which oppening i should build su-76 and against which threats? Only with timings please.
I think thedarkarmadillo got the point at post #158.
Not all units are bound to be "opening builds" units, because that removes the reactive part of the game at all. Its like rock-paper-scissors but with more steps.
In the current game, after many patches, a few kind of unit design still persist. They are not mutually exclusive.
Opening build units
, for standard, risky or safer openings. Mainline infantry and core units are included, even heavy tanks can fall into this category.
are those you only ask if the other player has shown a clear strategy, I.e. mg spam, go for indirect fire. Infantry blobs, go for HMG and rocket arty. Panic puma was another example. SU76 fits this category right now
Meta game units
are units seen most often because a balance or meta game favors them, JLI
spam because they were OP, command panther, bolstered infantry sections, dodge car and cav riflemen
. They sometimes exploit cheese or game unbalances, the meta game is about the surrounding aspects of the game in order to win. Its like using the game rules against itself.
Because SU76 is already known to be a reactive unit, its worthless to mention it as a opening build kind of unit. Therefore the whole question lacks of sense.
SU76 was an opening build unit before, when it had free barrage simply because you could spam it easily. The nerf su76 got, put it into the reactive unit design, as it was intended IMO. If it needs a buff it should be focuse towards the reactive unit design.
