PLEASE! make the chest opening titles account based! Gold ID title would also be very nice to have account based, but it's more of a convenience issue.
Why should I get less benefit opening chests on a map six times if I do it once on each of my PvE characters rather than six times on a single PvE character? Maxing the titles is a significant amount of time and gold either way - Please stop penalizing those of us that want to play and open chests we find with more than one character!
I think the title idea, for the most part, was a great one! It gave people with many different interests and goals something extreme to work towards. The titles never hurt you if you didn't care to work towards them. But first with the addition of the salvage save chances affected by the chest and gold-id titles, and now with the lockpick retention chances more than ever, I find it short-sighted of ANet that these titles are character based. How is it more in the spirit of the game for us to get more benefit doing the same thing over and over on one character rather than doing the same thing on different characters?
Do the people that put so much effort into maxing the title on a single character honestly care that much if someone who puts as least as much total effort on different characters have a title like theirs? Is it such a horrible offense that having the benefit of keeping lockpicks and salvages on their own other characters wouldn't make up for it?
If there's a valid reason for these titles (and therefore their PvE benefits) to be character-based rather than account-based, would someone please explain the logic of it?
If the people with single-character max chest and id titles are really so fond of them, then I propose a new pair of account based title tracks be added with our account's total chest and id numbers. Use these new titles to calculate the odds on salvaging and lockpicks. I don't care if we can display them or not - I want the odds, not the text.

I don't really care one way or another about most of the titles being character or account based. I max the mapping and mission titles on my "main" character, but that's for me. I don't mind that my other characters can't show them. LB titles do provide significant fighting advantages in PvE, but those do make sense to me as being character-based. I wouldn't mind them being account-based, but it doesn't seem wrong to me either way.
Thanks! (Hope the folks at ANet are still reading this forum and this thread.)
