They are tempting, but as you wrote not always the best fit. I mostly play in GF frays for brawls these days (and have 0 GF Gladius cards) but before I thought one should always use Gladius cards if available. I quickly learned that they should compliment your strategy or battle plan rather than be the centerpiece. Good read. Sharing this on https://twitter.com/PraetoriaDigest.
RE: Gladius Cards are irresistable, but should you always choose them over others in Brawls?
