Some perspective, huh? You have a clipboard map, right? Bring it up...the base identifier, C232, is right next to the boat you're flying over. If you fly over a CV and they shoot at you - its enemy. What relevance does knowing what base a CV spawns from have once its out to sea?
This excuse of "Its a game, not real-life" holds no water. If your argument of "its a game" was held, then we'd see pink P-51s, Tiger tanks with NASCAR logos, and Red Bull sponsored Lavochkins. This is why HTC has standards for submitting skins, this is why we don't see F-14 Tomcats dogfighting with Zeros (whaaa...but it happened in the Final Countdown!!)
Sure, we need ID tags, because there are people out there who can't tell a Tiger from a Sherman, and the way its set up, anyone can fly or drive anything. If this were an Axis-Allied situation, I'd fly without tags completely, knowing that anything Axis (or Allied, depending on who you're flying for) was the bad guy.
So let me ask, are you against pink P-51s and Red Bull Lavochkins? If you are, then why is it ok to put the number 242, or 78, or 59 on a carrier? Its equally as wrong in my opinion. Let's for argument's sake say we put the number 68 on the ship, since it spawned from P68. Woohoo, we now have the USS Nimitz in a WW2 game.
