Remove GA from ARURF

It makes the already nearly unkillable champions, unkillable. So when they somehow manage to mess up, they do not actually get killed. When behind, no one gets it because the stats are not of value appose to core items. URF is about spaming abilities, quick pace kill/die/revive and having fun, but when 1 champion is able to simply 1v4, 1v5 because they are busted (Mundo, Ekko, etc...), and then they get GA, there is no more fun or spamming abilities because you cant even kill your target unless they mess up massively (like diving fountain massive or forgetting to use their abilities).
