It actually makes it more of a challenge than walking into a gym with a level 43 blaziken and high kicking the hell out of everyone. Young trainer Ash and his new friend Goh become research fellows at Professor Cerise's laboratory, traveling all over the world to learn about Pokmon. I just beat the mauville city gym with Pokemon at level 27/28 and the guys to the north afterwards with a 6 Pokemon team with low level 30,s using tactics such as a lol 23 toxic spike with focus sash then only 3 Pokemon around level 32. So I put in a ttar not necessarily to kill things,but just to soak up some hits or whatever while my under levelled team get healed up a bit. You and Lillie must travel across an Alola filled with Ultra beasts to help restore Lusamine to her former self. Lillie returns to Alola after failing to restore Lusamine, only restoring part of her body. Pokmon Star serves as a sequel for Sun and Moon.
So it actually takes a lot of skill to beat a gym when the opposing team are 60-70% higher level than you are. Note: Pokmon Star is meant to be used with the CITRA emulator Pokmon Star is a mod for Ultra Moon by Rusyaas. However my Pokemon start the gym battle at level 8 otherwise after 1 victory they start to loaf if I go in at level 10.
Yes the gym is designed to be beaten by your own Pokemon at lol 16. I find it more fun to use the Pokemon I want and bred (albeit in another game) as they are IV perfect with egg over etc, otherwise these Pokemon will never get used! Ya I know what you are saying, however in X Y I bred a load of fine young Pokemon and wanted to start a new game with them, starting at level 1.
