The point of MK is that most of the packs come from other stuff. Beating Bloonarius level 20 on both cities will earn something like 60 packs in total, plus 16 or so ancient packs. Plus 40 packs from the Bloon Beacons and 13 from the fact that the Bloon Beacons may give 2 packs. This does take some effort, but MK packs aren't the only reward on offer.

Besides, some of the upgrades are REALLY powerful. Think ninja level 3 (pierce +1 - 25% more power) and 5 (bloonjitsu throws extra shuriken).
