I showed this guide to my friends and thez agree with me the purple text is OK. But I will change nevertheless. I also disagree with the supportive way. The only supportive item is the Abyssal Mask and in the items explanation section I not recommend it as the item you pick most games. You mainly build YOUR HP like tanks while picking damage items as secondary. The role of a support is to empower the others by heals and shields. The role of a tank is to protect carries by absorbing damage. This is what the build is about. Casual support items empower your empowering abilities. You have none. This is rather HP + damage build in my opinion. If you disagree write what is supportive. On the other hand, I will change the name and design of the guide. Thanks!

I recommend not using purple text, as dark purple on dark blue ruins my eyes :D You need to change the name to something like "Gragas Support OP [S5]", since you are building Gragas as an support. Remove some of the spacing lines, and change the name of the build. Other than that this is a great support Gragas guide.

Your mastery tree setup isn't possible. you have points in things that need a full set in the previous branch to be able to put any in the next.
