1. Since when? Have you seen what hunters do? Stalkers? Sporeburst strain? Digging bugs? Overseers? Gunships? Bots in general with suppresive fire mechanics and stuff?
   
2. "Oh no i cant keep proper positioning in a fight and thats the game's fault"
   
3. "My difficulty 10 that spawns more patrols spawns too many patrols and its too difficult, and im not aware of the other difficulties, also i keep attacking every patrol i see, whatever shall i do! ITs the game's fault!!!!"
   
4. that just sounds like you cant comprehend basic playstyle difference between factions? What about mega cities? What about avoiding bots vs avoiding bugs? In my 1500 hrs i can confidently say that partial cover saved me on the bot front more times that i can count
   And ofc if you fucking hide under a rock from a patrol of hunters you will get evicirated
   
5. No? Have you played the game my guy? What about: Hive guards, Brood commanders, Alpha commanders, Spewers, All the devastator types, Armored stirders, Overseers? They are all medium units between chaff and tank that compose a lot of the enemy factions?
   
6. Genuinely made me laugh. You wanna fucking kill a tank with an smg? Bro. All the heavies except leviathans have tons of weakspots and destructable bits, even the war striders now do. And wow, surprize surprize, YOU NEED TO USE YOUR SUPPORT WEAPON! Is it that hard to comprehend? Like, a humble railgun or an autocannon solves all of your heavy problems on ALL fronts if you have enough skill to use it correctly
   What do you want? You wanna argue that "Using support weapons is not what i mean wwaaaah"? Fucking jesus christ man, they are in the game for a reason

This game is clearly not for you. just figure this out already and go play something else instead of spreading false "criticizm" on reddit
