I've seen a few discussions on this from before the game released and wave1 expansions were known. I'm wondering what your thoughts are on this now?
If you had just bought the core set for legion and were looking to get towards a 800pt army of both factions (playing with family so I need to buy both). Do you think a 2nd core set is worth buying?
I'm thinking in time we'd get the AT-ST and maybe landspeeder and an extra commander for each side. However it'd be nice to do some full point battles in the mean time. We're going to want more dice, speeder bikes and an AT-RT which the 2nd core set would cover rather than buying individually. That would also provide 2 extra units of troopers per faction. Looking at the individual costs $25 for speeders bikes, $25 for AT-RT, $15 dice That's $65 before you consider the two extra units of troopers per faction in the core set.
Whilst longer term we might not end up running 4 stormtrooper/rebel units, perhaps having 3 + a specialist units, that 3rd unit for each side would still amount to $50 in expansions.
It seems at least as far as buying base trooper expansions goes, especially with wanting to cover both factions, the value is still there for buying a 2nd core set.
Only downside I can see is you miss out on some upgrade cards but I believe they can be picked up in other expansions such as fleet/snow troopers or commando's? Are there cards in the AT-RT or speeder bike set that are not covered in other sets (such as AT-ST/Landspeeder)?
