70 + tactics will break 100. They don't want you to AoE permastun by layering this on top of Dire Charge both at 120 DC. Builds like mine built with 4 different AoE stuns are why they won't allow all 4 stuns to be at the 120 DC level.
As a self-healing hybrid class, DCs aree never going to be fully workable. Always marginal. Fighter needs the DCs because their self healing is far more limited.
