Dog Tag prestige is ruined

I know that people want the "portal", as it allows for fun custom experiences and more casual gameplay which is great. However, with that sadly other features have been significantly ruined. Allowing portal servers to give FULL progression to EVERYTHING has made it possible for people to farm Dog Tags while playing vs bots. This results in tons of people running around with for example the Marauder Dog Tag, showcasing their highest multi-kill being 100+. What would otherwise be a cool Dog Tag to grind for and showcase, has now turned in to a complete meme, taking away all the prestige that comes along with it. 
It's EXTREMELY disheartening to obtain this Dog Tag the legitimate way, just to see a bunch of people flexing the exact same thing but with insanely inflated numbers. 

I'm all for portals giving full progression when it comes to overall exp, weapon progression and even challenges to be honest, but can we leave just a tiny bit of the features out of it, so that the game doesn't end up having 0 interesting achievements to strive for?

Even now it's probably too late, as I very much doubt there is any way to take away illegatimately obtained achievements, which is incredibly dissapointing to see.

Just another feature that has been completely ruined due to incompetent oversights.
