I agree with you 100%. I find that most of the time the biggest whiners are part of a very small, very vocal minority. I get my ass handed to me by lock box ships on a regular basis when doing pvp, but you dont see me on here calling for a lockbox ship nerf. Instead I learn how to fight.
The tricobalt mines are powerful, but they aren't the be end all. They have a one minute cool down between uses, and if you are unable to get your mines close enough to the enemy, thats a wasted volley. You cant give me any good reason why trico mines should be nerfed
