Even if you have AR operation/sharpshooter/proficiency 5 and you log in the next day to find all your fits are invalid because your Gallente logi, along with all logis get restricted to sidearms and no forewarning from the devs?

I always keep thinking you run Gallente logi for some reason, my fault. But anyway, you're missing my point. If you invest your SP into something you should be rewarded for what it brings. But the cutoff is that we have bugged skills, skills that don't work as described in the text and things that are changing overnight without any indication or forewarning like the series of ninja nerfs vehicles are going through. I'm with you on you should life with your choices, but if those choices are misinformed or baited and switched by CCP's influence breaking the 4th wall of New Eden's rules, all bets should be off if it's so drastic that you would have never made that choice to begin with since the outcome was altered.
It's like buying an apple but it gets turned into an orange when you bite into it and the vender you bought it from tells you to deal with it.

So just like AFK, the best way to play DUST is to not

Got it.

But why should Cosgar change his playstyle because CCP decided to nerf a perfectly balanced weapon?

I'm sorry that some of us have foresight and would actually like to see the already terrible player retention increase, as opposed to decrease.

Just because something is a design choice doesn't mean it's automatically right

You didn't, but what you're saying is don't use your SP because CCP is unpredictable and doesn't communicate decisions like this with us. So instead of playing the game and using your SP to enhance your experience, you sit on it, in the hopes that CCP gets something right SOONtm.

AKA, AFKing with your SP

Do you not pay any of your bills, and just sit on all your money until you think you have enough to make you happy?

Laser nerf was in the patch notes, MD nerf wasn't and no info on bugs because they obviously didn't test it. Also, laser still gets kills, play with Jaden once in a while...

No weapon should be nerfed to the ground though. And you shouldnt be OK with that unless you are just a FotM weapon user who loves searching for the next OP. All skills should have use or be removed.

I could easily say, I want to "adapt" that SP in another area I use weapons I like and others that I find fit my playstyle. I really dont think its right that I should have to jump through hoops to use them or abandon them because of some silly axiom this game promotes.

Adapting should be tactics not finding out your weapon now shoots rainbows.
