Lets try to fix the game. This game is actually stuck in 10-15 pokemon options in vgc.

1) Fix group eggs. (ralts family in amourphous group egg? c'mon!) and if needed, create new ones.

2) when u breed, base stats must mix in new poke. Fe:
Cyndaquil: 39/52/43/60/50/65
Chimchar: 44/58/44/58/44/61
kid cynda: 39/58/43/60/50/65
kid chim: 44/58/44/58/44/65

one stat is replaced completely from another specie.

3) Female can breed both species.

4) a pokemon cant have 6 iv or 5 iv at 31. 4 is max. and the other 2 cant reach more than 20.

5) Fix the weakness type table.
Landorus example. it is ground and flying. Flying must win the waekness, so thunder must be, at least, capable of hit him.

6) Wild pokemon must be influenced by: day of week, atmosferic time, month of year, etc. and ratio ofc. I mean, only in spring, pokemon like cherrim could appear.

7) stop pokemon level. Trainer level instead.

8) some attacks have doble use. Offensive and deffensive. other have doble power in offensive. etc.

sorry about my english, hope u get the idea. :)
some any more ideas?
