ngl that's just a skill issue. if your only out to a sweeper is hoping they don't tera defensively, then either you misplayed or your team just has a horrible matchup into said sweeper. if the sweeper does that without either of those factors, the sweeper itself is the problem. I think tera itself is a net neutral to the metagame, as you can usually answer a tera with your own, but tera blast is unhealthy in that mons can just get whatever coverage they want. your defensive check that can take any move from a mon shouldn't be able to just be blown up, because a defensive check being your only check to a sweeper is much more reliable than an offensive check being your only check. idk maybe I'm just yapping.
