I'm a level fifty f2p, and I'm having a really hard time making any strides with my arena rank. Obviously, I haven't had as much time to develop a team capable of playing defense as some others, so, after getting up to around rank 750 each day, I fall all the way back to about 1750. So, my question is, should I use crystals to get the extra 5 plays so I can climb higher and therefore fall less, leaving myself some opportunity to make some actual progress on the leaderboard? Or should I be patient and simply wait for my squad to become developed enough to hold its own on defense? Any thoughts are appreciated, thanks.
