Only listing some interesting 5-piece bonus that might make hybrid work better.
1.two side of mirror. In combat, if you used your mag/stam and then stopped using that resource pool for 15s, you gain major endurance/intellect (the one you didn't use)until you use that resource pool again.
for stam/mag players, stop using main resource (stam/mag)for 15s affect a lot of their performance in both pve and pvp, but for a hybrid, it's good to have one pool regenerating faster while using the other. Either hybrid tank, dps and maybe even healer can benefit greatly from this.
2.Final moments- When use an ultimate, transfer each your minor buffs as x spell&weapon damage, and each major buffs as y spell dmg&weapon dmg. You will have the damage buff for 15s, and while it's active, you can't receive any minor or major buffs. Might enough fun for non-hybrids, but adding both will make hybrid's both abilities strong
