People are free to deviate as they wish, there is no specific deviation as its everyone's choice. I will say definitely get tetra before 3rd, I honestly think its hands down the best to do.
I mean, I can mention rally as something you can get if you want, but I never wanted my guides to be something where I have to hand-hold with everyone, but more as a guideline for new and the old and as you get more experienced and know what type of skills you want after 3rd, then you can decide to deviate or stick to the build.
