Use a tm on lick BS snorlax?

Yeah, go for it. I mean, defense seems almost meaningless right now, but once your priority attack guys are set, why not?

I immediately used my first fast TM on lick BS snorlax. However, now I wish I'd saved it for an attacker.

I agree with aqua. If you've got nothing else worth using it on then go for it, but there's not much point to improving your defenders right now.

Use your TM on other attackers/defenders, Lick + Body Slam is the best offensive moveset for dodging and not so bad on defense.

I'm personally hoarding most of my TMs now. I've only used two, both on attackers.

I'd keep lick. Defensive moves don't matter at all and lick body slam could be an amazing PvP moveset.
