Well, thank you all kindly for the helpful and sage advice! I'm not the world's greatest expert when it comes to Fighty Bear - not only because mine is only at Level 6, and so barely worth spending the Pet Food to activate it, but also because I'm sincerely non-competitive by nature and thus never actually run out of Troops due to any sudden urge to feature on the leaderboards... in my low-stress little world, earning useful amounts of individual and FS-level rewards from Tournament = good; but spending more time than is absolutely necessary moving things around a hex grid = bad.
And so, being who I am, I only planted Mr Bear in my City at all in the hope of (a) one day advancing him to the dizzy heights of Level 10 (please, nobody suggest that I will win more than one Fighty Bear Artifact in the Spire, if indeed they do appear there at some future point... I will break down and cry!), and (b) because I am disinclined to log in any more frequently than I have to, so being able to produce more Troops at once (as opposed to more overall, which I never need) also = good... especially as the Bear-made Units are, indeed, free of cost (now that I think about it, that's
extra-good!).
In fact, I only posted the image as a joke, originally, hence the pretty silly title of this thread and the less-than-serious - well, so I thought! - content of my post, too. And I even intentionally spent all of my Supplies building Troops until there was only one solitary Supply left, just for the sake of taking a fun screenshot... moreover, I remain rather disappointed that the game wouldn't let me take the total down to zero, which would been even better for my purposes! However, I know that what I consider amusing doesn't always quite match others' sensibilities, sadly... which is why I said, upfront:
... so here's a rhetorical question...
But hey. I'm sorry to waste your time, everyone, and I'll remember not to inflict my bizarre sense of humour on the Forum too often in future...!
