To me, all this sounds like is that you use a sandstorm team and you're defensive over it's legitimacy.Like Electrolyte said Snover counters the main sand core of 3 pokemon. You have 3 other pokemon to beat Snover well they have 5 pokemon to beat those 3. Snover counters the main sand core while the other 5 beat the pokes that threaten Snover.
You may say I have a pokemon that beat snover and you have stealth rock ,but guess what there is a Spinner and probably a pokemon to beat the pokemon the threatens snover.
In the end all I can say is that sand won't be banned.
Essentially all your post is, is recycled points about Snover defense in a poorly constructed manner of which have already been dealt with.
Hippo is a reliable enough stealth rock layer to be able to continue to lay stealth rocks throughout the game. On top of this, the high paced offense of sandstorm teams provide little room to actually get a rapid spin off. Most spinners are also physical so walled by Hippo which can re-lay stealth rocks (bar Staryu, of which is spin blocked by Frillish and checked or countered by Lileep.)
Please read the thread again because I've already mentioned that I am aware sand will not get banned.
