Which character(s) have saved your rear ends more times than you can count? basically, who is the real MVP of your roster? For me it is Rex and Sun Fac, as a F2P getting Rex in a chromium early on was super lucky and fortunate. Then once fleet came out i started on sun fac, and geared him up asap. Currently have them both at gear X and 7 stars. These characters are KEY in my arena and GW, and are irreplaceable.
