Anyone else using lower IV raid caught legendaries/Ttars as disposable gym attackers?

Kinda foolish imo. During the regular-interval, double-candy events, low-IV Legendaries worth double candies.

No, but I did use a raid caught Ninetales as a disposable defender to save a revive, and I might continue to do that with other low-IV, relatively low-value raid catches. Not legendaries or T-tars, though, for the reason pikamander mentioned.

Time is more important to me than conserving potions, so no, I just use meta attackers. Raids give so many healing items that I'm not in any real danger of running out.
