What I find out of most posts on this forum and by extension Official forums (this happened for WoT too) is that most players have no idea what they want from the game, it often works like one unit has been unreliable in a game and people complain about it, either that or they get rolled over by a unit and then complain.
If there isn't any reasoning behind the OP that encompasses several reasons, its usually a waste of time.
Unfortunately, bias and fanboyism tends to make the really good posts (like yours) get turned into relative noise because its a lot easier to post on something that's definite and polar than something that requires you to think

Just a few replies to your OP
1. Vet 1 cap point is really useful, it can win or save games sometimes

2. I'd agree with pathing of vehicles being terrible, infantry is passable though.
3. Relic really do need to do side armour, not sure about angling though because unlike MOW, you don't have direct fire controls so relying on AI to do that will open another can of worms.
4. Yes to custom hotkeys
5. More sidegrades needed, yes, similar to VCoH
But yeah, I feel relic worry too much about the stats to the point where they only look at the stats, rather than focus on faction design during balancing. That has been apparent in most of the recent patches tbh.
