It was definitely 2/encounter in 2.03.
Well, this Brisk Recitation thing kind of puts INT in a rather ... peculiar place with Chanters, now. You either keep it a 10 and try to chant as many phrases as possible so you can cast, or you pump it and you have an unavoidable ability that runs counter what you're trying to accomplish.
My bad then ( again ).
As for chanters, I'm afraid I'm missing something: don't you recite a phrase, then linger starts and you move on to the next phrase? I don't think INT ever affected recitation time, otherwise increasing INT would've made casting slower.
So increasing int with Brisk Recitation still increases the duration of the buff by the same static amount, and while the total duration of the buff is shorter, you can also chant the phrase more often.
By the time you're level 16, for example, you can chant twice as fast: just cast the same buff twice and it will last as much as it used to and generate twice as many phrases, while taking the same time to recite.
