I have two actually - 1 is not farming Rey earlier, she is still sitting at 4* for me and I see a loooong grind ahead even with Guild shards.
The biggest one I just did and it is seriously bumming me out! I got a $50 iTunes gift card from work, had a big month. I bought the May the 4th pack and wanted to see what the Chromiums were all about as I was F2P besides Ewoks (see where this is going???) and I get a whole bunch of characters that I can never ever level up!!!
I got some cool ones - I now have a 3* Sun Fac, 4* Aayla and a 4* Leia. None of which I can use at those levels. Got a 2* Fisto too along with a bunch of Maul shards but no Maul. Oh - got Cad Bane since I had a bunch of shards from the monthly log in. Again, cant use him.
I could have been stocked with crystals for a long time but no... I was stupid (they censor 5tupid?). I was hoping for Rey or at least somebody I could farm.
The best/worst part which is one reason I did it? My kids play this game and they bought a single Chromium with the 500 crystal bonus. They got a full 4* Old Ben!! I would LOVE him on my team and I can farm him afterwards.
Oh well - $50 gone in no time flat with really nothing at all to show for it.
