This Modpack makes Pixelmon more convenient.
Do you want to catch the legendary Pokémon? There is a Nature's Compass for easy exploration and a Waystone that can be easily moved by the once found biome.
More food (Pam's Harvestcraft), more building (Macaw's list of awesome mods), more information (JEI, JER, Journey Map), just straight up more fun.
I recommend installing Optifine 1.12.2 with this pack, to add further optimization. (You will have to do this manually)
