So, I keep hearing everyone recommending focus fire, focus fire, focus fire, especially to people breaking into the game that are struggling... I'm not a big fan of focus fire, but rather I prefer to maximize the damage. Now, let me start by saying that I will try to focus on one person if all shots are equal...
For example, if I'm running an XXBB in a 2x2 block, I'm going to be choosing someone that all 4 can fire on, and in that case, I think it would be silly to not focus fire.
But, on the contrary, I often like to play lists that don't rely on formation flying, and as such, I might have my A wing coming up the right flank, my Y wing running along the left flank, and an X and B shoring up the middle. Perhaps their most dangerous target is Wedge, I'm going to have my X and B focus fire on him to try and take him out... but my A might only have a R2 shot through the asteroid on him, and have a R1 shot on the B wing behind Wedge... Unless my A wing can put the final point of damage on Wedge, I'm going to take that shot on the B... I'm going to do 1.88 damage compared to .43 damage on Wedge... In all likelyhood if I shoot Wedge, no damage will come from the shot, whereas I could easily do 2 damage to the B... in my opinion I'd be silly to do 1 more damage to Wedge.
Likewise, now my Gold is firing, and once again, unless he can get that kill shot on Wedge, I'm going to shoot at the B wing, or something that's out of position. If I can ionize that B and then swoop in behind him and take him out of the fight, that's a better use of the Y wing than doing 1 more damage (which in all likelihood will just cause overkill next turn as my X+B focus Wedge down again).
So, am I an idiot for not focus firing in favor of taking the best shot each turn? I realize that means potentially more guns are shooting at me the following turn, but I play the odds and say that an A wing is unlikely to do 2 damage to an X at R2 obstructed, so I might as well not waste my shot and get 2 damage in on the B as a head start on killing the B.
What are your thoughts on focus fire vs. best shot available?
