You can ignore Snowdrop though, it's generally the worst island, and just let area bonus overflow into it whilst going to the islands that actually matter.
That said, there's a good chance your core teams may end up being Water for CB, Fire for TH, Grass or Psychic for LL, Electric for OGPP, due to synergies with legendary Pokémon and the ease of access to many of these types thanks to starters in particular.
This does mean that you may end up neglecting Fairy and Flying for CB, Ground and Rock for TH, Fighting for LL, Steel for OGPP (Ghost is good), this was my experience at least.
Ultimately though with EXGG it's just biting the bullet and suffering the low expert bonus for the first few weeks. Even when you do finally get your expert bonus up, hitting Master 3 each week still takes effort.
>>58852440Since they did away with the inventory penalty, all you lose out on is a single skill level, for which is moot on a berry specialist even with as good of a skill as Tasty Chance S.
Even better is that befriending Weavile bypasses an evolution item cost of 1400 sleep points. It's a factor in why I haven't invested in either of my BFS Sneasel.
