I mean if you're losing to troopers and your only option is putting speed on a Bossk to beat them, go for it. But you're cutting the potential effective health of your Bossk by over 250%. If your Bossk has 50% armor and 100k health+protection, the opponent must deal 200k damage to kill him. If your Bossk has 80% armor and 100k health+protection, the opponent must deal 500k damage to kill him. With g12+ or g13 bh, with 1-3 defense sets each on them, nobody will kill any of them first turn. Bossk taunts and for the rest of the match he can outheal their damage. Everyone has tried Bossk with speed, it's good for imperial troopers I guess. BH stacking defense can destroy pretty much any matchup, except it has a tough time with Nightsisters, and Malak. The only people who argue with me are people who haven't tried it, the people who have tried it use it.
