Leap slam Scion

can someone check out this skilltree and tell me what i can change? This is my first build ever so i dont know which passives are not worth to take at all, my plan is just to be a tanky leap slam scion but also dealing nice damage by getting alot of str + health on gear + passives, passives will give me 490str and i will easilly be able to get to 800-900str with str on gear + astramentis. I havent decided what skillgems to use on leap slam but i dont think the passives matter for the support gems? im planning on using CWDT with Endurance charge + Molten shell. Ill be using Grace (thats why i take Iron reflexes) + Purity of elements since im not taking any resistance nodes because i will be able to get it all on gear + aura. I will be using this in Softcore but since its leap slam i still want to be tanky since the 10% exp reduction is not fun C: Also im not sure if its worth it to take some attack speed nodes but i thought it would be good with leap slam?
