Yeah so I am pretty much exclusively an Imperial player, and thinking back I'm pretty sure the only other time I played a rebel list was core box learning scenario while demoing the game...
I went with a Neb B (the one where crity = dmg x2), 2 heavily upgraded MC30 torpedo frigattes (for testing purposes I put expanded launchers on one and APTs on the other, both had XX-9s and ordnance experts) and Dodonas pride CR90 with TRC, fighter screen of 3 YT-2400s and 2 A-Wings.
My astonished opponent was my long-time rebel playing partner, I had him try to guess which Admiral I was using and even being an exclusive rebel player he said D-man last. I assured him that I would have to have a long shower with steel wool and Javex after playing filthy rebels.
He was running a heavy bomber list with what seemed like every ace in the game. Jan, Nym, Luke, Wedge, Dutch, Dash and a generic x-wing maybe more, I's have to check...
He also had Jainas light CR90 with TRCs, an MC80 Carrier and an Yavaris led by Reikaan.
I had initiative and decided to go first as I knew he liked precision strike in his objectives and a crit focused dodonna list would be happy to go toe to toe with those bomber victory tokens, I also figured double activating an MC30 might be disgusting at some point.
The match opened very cagey, he deployed the MC80 obliquely and last (he had placement advantage from squads) but i deployed my MC30s on either side at high initial speed thinking to pincer in. I spread out my fighters to discourage him from spliting his all other ships deployed centrally.
he did a great job in his initial movement to give me no good choices on tying down his bombers, anything i did would get my squads nuked way too early so I had to allow him 2 or 3 rounds of virtual freedom with bomber movement.
my MC30s took a reasonable beating, my CR90 died and so did the Neb-b (unfortunately I got the crit that burns a def token and he kept flipping it till i had no defense!) but the highlight was the successful pincering of his MC80. My Neb B and CR90 did his CR90 in pretty handily but yavaris and the MC80 and bombers blew them away. but after some great flying around round 3 or 4 I had my expanded launchers intel officer MC30 set up for double arc inside the front arc of the MC80 preventing him from moving and my other one side arc to his rear. I double activated the one in front for 4 heavy black and blue laced shots. I think the MC80 finally flew away (after I flew through it) after having sustained enough damage to almost kill it twice. It was disgusting.
I ended up with 18 tokens to his 14 and all his ships destroyed resulting in a 9-1 drubbing...
Thoughts on Dodonna:
-XX-9s on high damage output ships with Dodonna is a high-return synergy.
-Dodonnas pride is OK but not too amazing, with Dodonna it can be very worth it when your little 2 blue 2 red CF front arc that normally wouldnt get through the opponents shield rolls 1 blue crit and you discard it and hand your opponent just the wrong crit with a shirt eating smile on your face.
-I tried to play while observing the impact of the admiral, and to be honest, while it was a crit-fest of a game, I only remember sifting through the damage pile 5 or 6 times before he died. His ability lends itself to small based ships. Total hitpoints for 4 ships was less than what im used to for a 2 or 3 ship imperial list and when i consider the actual IMPACT of getting to select the crit vs just handing out boatloads of crits thanks to XX9s etc I would say the impact was fairly negligible. In other words, the list would have won just as handily without dodonna as with dodonna. This means that his point cost at the lowest for rebels is probably correct, his costing 20 points and the upgrade wiggle room he allows on otherwise expendable, fragile ships you would hesitate to stack points on in other lists provides sufficient value to consider taking him (if for nothing else, to confuse people who can't name more than 3 rebel admirals.)
In conclusion:
-He is costed correctly (IMO). Low point cost for low guaranteed return (yes, you might get that ONE time where you can choose a structural failure that just manages to kill a ship, but that could also have been 2 ackbar reds getting that extra damage through, or that extra activation on a dead ship that allows you to kill an enemy ship, which happened this game actually)
-He is fun to play in that while his impact is quite small, the psychological impact to your opponent is large. Your opponent may bend over backwards or play sub-optimally to avoid otherwise meaningless crits.
-I would play him again. In fact, much like my love for Ozzel because of how maligned he is, I think Dodonna is possibly very under-rated and under-played for an Admiral that is costed very correctly.
