Wave 7 - 4.5/5
The pinnacle of the game. The designers nailed it with the addition of TLT, crackshot and the amendment to the large ship MOv rule. The influence it had on the meta in my area (at least) was fantastic. It ended the dominance of two ship lists and boosted small ships sufficiently to make them far more popular.
I'm only not awarding 5/5 due to the Khiraxz and punisher being sub-par.
Wave 3 - 4/5 (when I began playing)
Wave 6 - 4/5 I had always wanted to play bounty hunters! Shame that the M3A was so poor whilst the starviper overpriced.
Wave 4 - 3/5 both the rebel ships were great additions, but it was unfortunate that overpriced the defender whilst overpowering the phantom. Loads of fun though.
Wave 8 - 2/5 a big disappointment as the mist hunter, TAP and ghost have been great additions. I personally think they've cocked up with the jumpmaster. Both dengaroo and Uboats are dull but disappointingly competitive, with the latter having far too much of a negative impact on rebels as a faction.
Wave 5 - 1/5 I did not enjoy turret wing whatsoever.
I'm not going to rate waves 1&2 as I wasn't playing the game until wave 3.
Wave 9 looks great to me, even black sun slicer tools, but my concern relates to the overpowered or underpriced jumpmaster and how the new cards could further improve them.
Wave 10 - I have no problem with it. Nothing looks broken, whilst I've been itching for Kylo Ren's shuttle ever since the movie. I'm very relieved that the rebel tie fighter only contains unique pilots. Tie swarm belongs solely to the imperials.
