Gen VI and VII with the Exp All made things much simpler. Takes away a lot of grinding so I really like it, but it does make the game easier as well.
I only had issues at the beginning of Pokemon Moon when I had no Pokemon to combat the Magnemite at the School. (Only had Popplio, Pichu and Pikipek at the time)
The difficulty in ORAS seemed to be lowered, but I think Pokemon SM/USUM was able to get the difficult right, by taking into consideration the EXP all.
Serves you right for choosing the worst starter
But still, situations like that are pretty interesting, even if there's only a 1 in 3 chance of them happening. I still remember the difficulty of facing Brock in Red/Blue if you started with Charmander.
