I wouldn't get Suicides at your level
I wouldn't get Suicides at your level If you disregard my level and just look at my top Champs?
I wouldn't bother with suicides right now. Not due to your roster but simply because you don't have enough mastery points. I'm not sure how many points you have in total right now, but it's very expensive (points-wise) to unlock the suicide masteries. In addition to the actual suicides, you also need three points in Willpower. Before you can even begin to consider suicides, you need to spend 15 points to unlock Willpower (plus three points there) as well as 15 points to unlock the recoil tree (plus one point in Glass Cannon and one point in Recoil to even reach Liquid Courage and Double Edge; and then six points in them). That's a total of 41 points. Add to that Parry and Dexterity and you're probably running awfully low on points, if you even have enough to cover it all.I would focus on unlocking Willpower for now. Once that's done, you can focus on the Recoil tree. However, there's no need to rush to get there.
