AH Guardian is still a powerful build and afaik still widely used in WvW, however most of the PvE playerbase has realized that a tank/healer isn’t necessary, and as a result most Guardians run Berserker and a rather offensive trait distribution, e.g. 4/5/0/0/5.
Shorter recharge for consecrations and/or shouts are usually the only defensive traits players pick nowadays.
