The wyvern's hoard pack is prob gonna ruin rank legend pvp and your prob wondering why. its the same problem back in CL test too many pips to start with. from my observation in Wizard101 central wiki i saw that the brilliant boots and Peaceful robe of the set gives an extra power pip at start (for lvl 60). I am wondering if you could replace that like Heal boost for peaceful and block rating or critical rating for brilliant
Wyvern's Pack doesn't give anything epic or ultra rare. On the real realm. Bring the chance higher. I agree with the second post, it will unbalance it if you keep asking for better stats. Try to stitch them.
