I always thought scouts being OP past a certain level was a bug. So if you want to play by exploiting it and saying it's bad, then that's partially on you.
I don't remember any issues with hit detection though?
Edit: Googling mostly confirms it? People are complaing about VC4's bad hit detection compared to VC1's.
Scouts being over powered wasn't a bug and I have no idea how you would leap to such an unfounded conclusion. Three scouts came with rng abilities that gave them another free turn at the end of their turn irrc. This coupled with orders allowed them to charge through maps with little to no issue and reach the flag in the first game. It was poor balancing plain as day. After a certain point your machine gunners can take out tanks making the lancers a useless class when their niche against tanks was already the only thing they were supposed to be good for.
I think because of the way it plays like a hybrid, people have expectations that maybe aren't in line with the actual gameplay and systems. I agree that many times it looks like your shots really should be hitting, but this is an RPG; one needs to remember that each shot is essentially a dice roll, and your perfectly aimed headshot doesn't guarantee anything.
While I agree there are times where enemies just drop to the ground but I have prettymuch never seen the reverse happen. It also kills suspension of disbelief and becomes meme worthy when enemies can be shot with a gun to the back of their heads and still dodge. As a hybrid it does everything wrong mixing parts that don't go together and come off as idiotic.
My secondary issue besides dodging and invisible hit boxes on railings walls ect blocking shots would be the weird physics the games use. I can throw a grenade as an example and it will bounce under the tank. Or the death tank maps where you use lancers and such to try and knock the rocks down and a rocket launcher will miss.
I've heard that before too and am not sure what people are complaining about. Unless they are raging when they shoot a sniper round too close to a fence and it gets lost to an invisible wall. I mean it's not a fps so people complaining about hit detection sound like they just wish it was one.
In vc4 scouts are squishy, often frustrated by grenadier interception fire, and have relatively bad weapons for most of the game. Their AP advantage is no longer as large due to a shocktrooper buff. Scouts still can be OP but mainly through an abuse of one of three things: Defense^ orders, direct command + double movement potential, and a certain minor-spoiler weapon gained at the end of the valkyria dlc.
Already mentioned above but yeah the weird hit boxes where I can shoot an enemy on a bridge and the railing on the bridge I am standing ons invisible hit boxes block the shot from me despite my gun being above it. But when the enemy fires back at me all the bullets land. Its inconsistent shit like that which is the issue.
