I just spent a fair amount of time going over the X-Wing spreadsheet that vadersson posted (a most excellent resource, so thanks for taking the time to put it all together).
It seems like it may not be worth buying more than one of the TIE and X-Wing boosters.
From the X-Wing expansion you are getting the R5 Astromech (the others ship or upgrade cards are unique so you can't use more than one and/or are also available in the starter).
From the TIE expansion, you get extra Swarm Tactics (but I'll get 1 if I get a single TIE expansion and 2 more in the 2 TIE Advanced expansions I'm getting -- otherwise everything is unique or in the starter).
Given this, it seems like I'd be better off getting just one of each expansion and adding another starter (that way I get an extra TIE and more dice etc. for only $5 more on Miniature Market).
Am I missing something? Are the R5 and Swarm Tactics better than they look (do I need more than 1 R5 and 3 Swarm Tactics)?
I'm considering changing my order in the next day or so, so any thoughts would be appreciated. Right now I ordered 2 of everything except the dice. I'm thinking of changing it to 3 starters, 1 TIE, 1 X-Wing, 2 Y-Wing, and 2 TIE Advance. Smart move, or am I better off keeping it as is?
