So you want him to not engage?
No, I'm pointing out that there's a double-standard here. The majority here is saying that allowing nametags would allow people to prey on noobs. However, that doesn't prove to be the case, because what happens in practice is that the noob (or lesser-skilled player) engages someone very skilled and they have no way to know that they're outclassed... until it's too late.
I'm not saying I want them to run, but just as in WWII with unique color schemes like Eric Hartmann's black tulip or the Redtails' red Mustangs, nametags allow players to identify each other. It allows new players to say "Oh yeah, that Zoney guy - he usually goes into steep, climbing turns and usually gets me. Let me try this new move and see if it works against him this time!" It encourages players to evaluate their skill and go into a fight armed with knowledge.
So you want to call him out on 200 or PM because you don't like the way he is flying?
No, it allows players to build reputation. When everyone sees X player refusing to engage, it universally lets everyone know "Hey, this X guy is horrible" and helps identify players who may not even be worth the effort in the future. On the flip side, seeing Y player take out 4 guys 4v1 lets everyone know "Hey, this Y guy is really, really good." Currently, the only way to know who people were fighting is to ask or get an assist.
This change quite literally allows players to directly build reputations, instead of through hearsay.
So you need to know who they are?
It's a competitive game - that's the goal, by definition. Otherwise, why even bother showing who you shot down? Why not say "SYSTEM: You shot down P-51D #3"?

See above regarding reputation.
