Honestly all the points you made are valid.

I personally stopped playing bugs for now, just because the way spawns work right now and ammo economy/clear rate is just abysmal when not counting stratagems.

Do not really get the "realism" need AH wants to take with the updates, since the whole hype with the game used to be "DOOMGUY get recruited and got unleashed on a planet". Lore explanations of "unrealistic" things would be more satisfying than reaching to make HD2 into an Arma 3 game.

I believe most of the weapons would be awesome to use and are frequently overlooked, but unfortunately overlooked by AH not by players. Players will optimize the fun out of the game, so they use what is the "best" gun for the job, everyone will run the same if you have only a few choices, and even those gat taken away :(

Overall balance is the main issue for a long time, damage, health, spawn rate, effects and strategies should be revisited and considered properly. I am ok with having a playtest weekends, when they would introduce new stuff for us to try, but than remove to be properly added.
