None of these matter to me really since the games rarely use those moves and often i already overpower them before i ever lose my strongest. and Terastal does cause lagging. But all of those pale in comparison to HM Moves from older games which i recommend adding.
It took 8 Generations for them GameFreak and Pokemon Company to finally decided to remove all of it, including the ride pokemon's.
The only good moves in both battling and on the map are Fly and Surf. But cutting down, prickly bushes, strength puzzles, rock smash, defog and flash.
And worst of all most of these puzzles don't leave in the older games with the exception of strength boulders.
