If it were a *different* title, sure. There's already different titles for completing Normal and Heroic. Adding a Raid Finder title would be fun (even if completing LFR is a more trivial task these days than completing a PUG Zandalari heroic :/).

While I was disappointed not to get the title, to be honest, I do think the raid achievements should be left alone to the normal & heroics. That's why they call it "Normal" after all - LFR is essentially a nerfed version. Why should we get achievements for beating the raid on easy mode? It gives some incentive other than better loot for doing these raids on Normal and Heroic --- not that I'm ever going to try Heroic!

And how about not being able to touch those daggers unless you're in a raiding guild? The devs don't seem to understand that the barriers they've erected against getting just the starter 397 daggers only encourage extortion. You want the daggers? Pay us 10k, then another 10k to get a questline started which we won't be able to complete until we're able to solo the raid, which might not happen for three or four years.

And before anyone says "If you're not a raider, then why do you want them?" you could say the same about 403s--aren't 397s good enough?
