Bolt charge doesn't change ttk much it's flashover that does. Btw at least there's counters to the barricade. A smoke bomb instantly blinds, slows, and damages the Titan behind it and the radius allows for an easy kill since it takes like 6 seconds for the Titan to get free. Throw a duskfield at the Titan for a similar result though they won't be blinded. Toss a scatter or really any grenade with decent damage. Shoot an area denial gl. That's how I countered it and it either destroys the barricade or both it and the Titan. There's plenty of ways to counter it versus last word which the only counter was a sniper across the map (Needed to be at least 60 meters), rdm last word, or a super. There especially wasn't any way for Warlocks to get around rdm hell rdm+last was so strong flashover barricade titans would die faster than they could get 5 stacks of bolt charge and even if they lived the barricade went down before the Titan could get full stacks.
