Sceptre mods for minion

Stats on sceptres for minions are heavily undervalued. Either the stats on the passive tree need to be toned down, or the sceptre stats should be improved.
For example, I rolled a T1 critical strike chance mod on a sceptre — a rare modifier (35–38% increased crit chance for nearby allies) — which is significantly worse than a single passive point on the tree, Necrotic Touch (40% increased minion crit chance).
This imbalance shouldn't exist. There's no motivation to grind for better weapon items under the current system.
