We by all means could have pushed them into the full on infiltration squad role (see commandos and stormtroopers)
I seriously wished that you have pushed. Their current camo is only working either you are there before your opponent (which in many cases won't happen since you will want falls behind the lines and those lines are closer to your opponent) or your opponent was fallen asleep on the keyboard and you got there.
I think they will not be overpowered or anything like that since they don't have the chrushing power of commandos or stormtrooper in CQC and are as you say glass cannons
With the current changes they will be even harder to use IMO. Let me explain why :
1- They start with Kar98s so at first they will need to fight at long range or will get destroyed by many allied units. (So at first they are bad right ?)
2- When they get their first upgrade they will want to fight in long-mid range still. BUT
a 4 man squad with identical survivability with Volks. We know how Volks face IS, Penals, Rifles etc. but that is 260MP spammable Volks not the 320 (with current changes) "Elite Infantry"
Falls. And also to close the gap to throw the infamous grenade they are not durable as PGrens or Obers to do that and will definently drop at least 1 model before throwing the nade.
3-When they get their second upgrade it is the Falls we currently know with a little harder punch. But I still
will they deal more than the Ober. (That must be the trade off right ? For survivability you get better aggressiveness.) Thus Obers still will outshine and outperform Falls IMO (And with changes Obers are also coming faster so I definently see no point of Falls).
I think for those reasons they need to get the commando camo without any changes to current survivability and be deployed at 3CP. Because it looks like only this change can save them from being an inferior Ober.
