but other than that being a super tank with pulls and stuns and stuff is pret fun.
Being a tank is fun but I wouldn't consider the support a tank. Usually I play top and then build into such a role, as Nasus or Garen. They're far more viable as tanks than Leona or Taric - you lack the income to make the items you need unless you're doing really well, and you have to gimp yourself to buy support items so you're not super powerful.
People also tend to complain if you try to build damage as support.
I like playing top tank far more.
