Major Issues found in Pokemon Scarlet and Violet

One of the Major Issues I find is as it follows. Scarlet Violet takes away iron tail as a TM move. I actually like Iron tail as either a tm and/or a tutor move. Another issue is that they have floatation device for Beartic, which is weird because beartic can use surf, therefore it can swim.

I wouldn't call these major issues. A major issue is something like the game being extremely buggy or glitchy or not working properly or being unfinished.

I get it that the game's too buggy due to the open world gameplay approach. However, I did refer to the previous Pokemon games that gen 9 should've incorporate into.

@PokemiiAC I wouldn't mind having Beartic Swimming. Although I'm betting that the frigibax line along with the Cetoddle line are the ones who can't truly swim.
