>>54439564There are plenty of fish in the sea competing for top dog, especially those who have been doing it since childhood. Why bother throwing yourself into that melee when you can relax with your buds? Might be for some, but I for one wold like to take it slow and steady each day. Especially if your mons synergize and compliment each others differences, and that of your own interests.
For those involved with gardening and farming, I would presume grass, ground, rock, and water types might synergize well with each other. Grass should be obvious for what they provide, ground and rock for turning and nurturing the soil, water for their ability to irrigate depending on the mon, and if you are out in the wilderness, fire might be useful for creating charcoal or other such things to help add further nutrients to the soil.
