Rogue was ok, I think it tricked Llamadeus into making Slasher and defenses when they should have been using Ravager. Shieldbot slowness compared to vehicle did not hinder you because Llamadeus ignored one half of the map, opting to spend too much on defenses there instead. Four Ravagers could have swept all that expansion away (and the commander) at many points during the game.

I'm pretty damn confident rogue is a good unit now. They are positioned such that they kill all light defenses +stardust, all riots, most assaults, and some key skirmishers.

I would not expect them to work particularly well vs. LV, since LV has 'skirms' that outrange it. But when you see them against cloaky or hover for example, their power is apparent. Cloaky can't standoff against them with rockos, they need to either dive with glaive or go long with spectre. Hover are in the same boat where they need to dive with halb/dagger, or go long with pene.

Shield now feels stronger than cloaky to me on smaller maps.
