"Metagaming" means considering external (to the game setting) factors when making game decisions, like using bugs to your advantage or having enemies act on information they could not reasonably have based on in-game sources. Making a random animal pick out a healer in a combat would be metagame (coded that way because of the developers' knowledge of player tactics) but an intelligent foe could reasonably prioritize support toons over attackers based on in-game knowledge and experience.
I would argue that dealing with an indirect threat at the expense of a direct one involves a logic that is external to the situation, and hence metagame.
