What you described, is an unintended exploit/glitch caused by some of Baird’s cards. Specifically the Bloody Support card; and the Precision Repairs card. Basically this applies the effects to barriers too so barriers cause bleed damage and on damaging and killing enemies it causes them to restore their own health as long as Baird’s DR-1 Ultimate ability is ready (just don’t actually activate it!) and he is holding a “precision weapon” - so a Longshot, Torque, Markzha or an EMBAR.
I don;t think TC have mentioned it directly in recent tweets or streams, but alot of us reckon it will be patched when TU4 drops, which will probably be next Monday or Tuesday.
