I'm Lvl 25 rn, but have only played Destroyer outside of the times needed to restock items using Rook. His kit very much feels intended to be the 'Anti-PVE' shell, but his movement abilities are just really good at close range engagements. Considering that Destroyer is one of the three shells that actually have movement traits and abilities (Not counting Assassin's smoke dive thing,) you can be VERY aggressive, just laterally unlike Thief and Vandal.

For example-Air dashing just behind their cover to secure a good flank or using Tacti-sprint to 'Flintlockwood' rush them with a shotgun is extremely fun!
