They would seriously nerf this, too!? This is what I hate. Balance and restart are already ruined and people want even more of the good skills to get screwed over.
Variety is a good thing. You're not MEANT to be using one of like 3 skills in every single deck you ever make. There's a reason not every character even GETS skills like Restart.
Beatdown PROBABLY won't get nerfed until 5D's is a thing. (At which point, given Synchros, high-levels would become much easier and more prominent than they already are.) But if it needs to be, so be it.
And then watch people complain about the field spell skills. It will never be enough and then there won't be any variety at all eventually as long as some people are relentless with the complaints.
