Monsters double in usefulness with every level up. With every level up, both health and DpS go up by (2^0.5)x. That means that a Lv.3 Ogre, will have 2x health & 2x DpS than a Lv.1 Ogre. And a Lv.5 Ogre, will have 2x health & 2x DpS than a Lv.3 Ogre. So a Lv.5 Ogre is literally 16x as effective as a Lv.1 Ogre.
So if you’re wondering whether or not to blitz the next monster dungeon… Do it. I, personally, like to raid dungeons during my alliance’s Ogre Boost time, and was able to progressively level-up my ogres, using ogres. Obviously you need a lot of leadership to do that, but, never underestimate the usefulness of monsters (:

Another fun fact I’ve found about monsters!
As stated before, monsters double in usefulness with each level. That also means that they’re only /half/ as useful for each level they /don’t/ have. The problem? They still cost the same amount of morale. So considering that a Lv.5 Ogre is 16x as effective as a Lv.1 Ogre, that means that every morale point spent on a Lv.5, is worth more than an entire Lv.1. With monsters being so weak to start, and in being able summon less of them, they’re almost useless in low-level gameplay.
In high-level gameplay, they’re not necessarily useless, as much as they are restricted. Whereas in low-level gameplay, you don’t have enough leadership to make the monsters last, in high-level gameplay, you have more than you need! Ergo, monsters get stacked up, and you can only seem to be using a maximum of 3 at a time.
But Goldy Locks tried mid-level gameplay, and it was juuuust right~ (:
At mid-level gameplay, you should be at the point where you’re strong enough both to max your monsters, and to create a small horde of them! Now you’re able to form your monsters into something useful that lasts, /and/ nothing goes to waste! (:
Conclusion? Mid-level players should seriously consider maxing and using their monsters for offense.
