no
pokemon was never as easy as sword/shield
yes, knowing type differences and the ability to use type advantage makes the game very easy but if you haven't noticed, in all the previous games, you actually have to know about type advantage because your rival will be there waiting to kick your butt if you don't
however sword/shield has your rival picking a team that you can wipe out with your starter.
bede is a little harder but he is always low on the pokemon count + exp share means that you will beable to kill him with your eyes closed
also the gyms in the earlier pokemon games were actually challenging too and it was something to look forward too, of course, this changed in x/y sun/moon sw/sh
now, the gyms are just fun minigames that seem a little pointless and dynamaxing is kinda pointless compared to mega because theres no stat/hp increase, meaning that i could just use 3 potions for the 3 turns the opponent uses dynamax and i wouldn't be missing anything
