I believe that Octillery should be at least C rank in this tier, u can patch up its only flaw which was speed by giving it swift swim, all you need is a great rain starter for example i use Ferrothorn for my drizzle user and i have swept many AAA teams with Octillery it makes great use on good rain teams. Not to mention its amazing move pool both physically and specially with decent 105 base power in attack and special attack.
