I agree with this wholeheartedly.
It's good but so are many other top quality pokemons in the OU tier.
Terrakion is a great A-tier pokemon but not a S one in my opinion.
I'd also like to say ninetales should be in S.
It's not as good as politoad or tyranitar, hell even abomasnow on its own.
But sun teams are by far the second best weather after rain teams.
And we all know just how effective weather teams are in general and how prominent weather wars are in gen 5. Many sun sweepers and abusers are heavily reliant on the sun, such as venusaur, and heavily dent on other weather abusers. These are all because of ninetales. It's true ninetales is rather a terrible pokemon on its own (and politoad is too in my honest opinion) but it affects the metagame far too much to not be in S.
