That was out of the place but the (now) bold parts says a lot, this fact of no complex ban should get a real big discussion because they have sense and currently no one is willing to change the stuff because they are "set in stone", what if it was wrong all along?
The reason that stuff is "set in stone" is so that we spend our time discussing stuff which is as important as possible (talking firstly about the game, and then secondarily about stuff like bans). Spending forever talking about stuff that is largely settled is a waste of time.
Anyway, I refer you to:
#1 the last time complex bans got discussed, in
this thread
#2 the
banworthiness guidelines, which is not yet set in stone, and discusses when stuff should be banned.
Within the banworthiness guidelines, there are a few things to note
#1 complex bans are not explicitly ruled out
#2 the guidelines are primarily focused on Pokemon
Also, I quote this:
Certain “cheese” strategies may undermine competitive play, as they may present scenarios where players could hone their skills and then lose regardless to questionable strategies which may require low amounts of skill to execute (e.g. SwagPlay).
This is the section which would be relevant to banning wrap. Now, does it require a low amount of skill to execute? In some cases, yes (Dragonite in 1U), and in some cases no (Dragonair in 5U), although it's not an inarguable point. However, does Wrap undermine competitive play? I think that is a very big stretch at best.
In two tiers, RBY 2U, and RBY 5U, is Wrap a dominant strategy, and in one other, RBY 1U, is it prevalent but far from dominant. In RBY 6U it is used but I'm not sure if one would describe it as prevalent. Partial trapping in a form other than wrap is prevalent in RBY 4U and to a smaller extent in RBY 3U, in the form of Fire Spin, and Clamp of course is prevalent in RBY 1U.
Now, does Wrap undermine competitive play? In RBY 1U, I think maybe there is a case to make, but it is tough. Firstly, Wrap Dragonite is pretty uncommon, but in fairness, when it is used it arguably does undermine competitive play and I don't need to explain exactly why that's the case, it's pretty clear. However, Victreebel also uses Wrap in RBY 1U and I don't believe anyone thinks that it undermines competitive play there. Of course, it is obvious here to bring up AgiliWrap, which I can come to soon. In RBY 2U, does Wrap undermine competitive play? I don't know, I don't really play the metagame. In 3U, 4U, and 6U it doesn't undermine competitive play, but by default. In RBY 5U, not only does wrap (and agiliwrap)
not undermine competitive play, if anything it
enhances it, making the game more strategic, creating a tight game based on control and determining and executing long-term strategies.
Now, does AgiliWrap undermine competitive play? In RBY 1U, maybe, in RBY 5U, it absolutely does not, and in RBY 2U, I don't know.
