I've been paying attention to Paul's stream (especially against scrappers) as well as Boyce, and a few others. The context of this clip can be seen multiple times throughout the vods.
Scrapper is absolutely overtuned in most 1v1 scenarios, there are clear weaknesses as well.
1 major weakness being it is not able to even decap a node from something that does not already decap it from itself (mesmer distortion) or has no sustain (curses scourge), any of the current meta side noders can perma neutral the point against it sans mesmer without any effort at all. A sword weaver can essentially afk, as an example. There are major threats to it in a plus as well even using it's most defensive options.
As far as it's 1v1s go, it's REALLY good at not dying, but only not dying.
Stop getting trolled by scrapper.
I think it's actually a very useful tool that will be forcing players to rotate correctly or lose. Also comp correctly, or lose.
