HIE adds some competition for leading shots on the larger ships, and some CR90B are gonna love it.
General Draven's presence will weaken A-wing spam somewhat and makes Dengar no longer an auto-include. This one card makes the MC30 much more multi-role than it currently is, IMO.
EWS looks rather attractive on a CR90A flagship, and harmonizes with rather than replaces Jaina's Light.
But the thing I like best about this wave is the way that the most interesting upgrades compete so strongly with others. You can't just staple in the new cards and suddenly generate awesomeness where there was none before it. Something else will have to be given up.
