Twitch, Yasuo, Trist, Akali, Irelia and Leona had it. The only one I actually question getting it is Leona. The rest get enough value out of 40 AD, 30 armor and the passive to make it completely justified. The ones who didn't were Yi, Nami, Lux and Cho. Yi had a BF sword in his inventory and was likely going to get it as a last item.
GA is now in a really convenient state if you are playing any champ that wants AD and a really effective anti burst passive. Arguably too convenient. And it only costs 2400 gold.
