I found this to be a complete exaggeration. There are many checks to Garchomp now, and if you are still afraid, just use Weavile/Mamoswine. Seriously, who does this that you have spoke are overestimating Garchomp. In fact, before this test ladder, I've battled with some pseudo-OU teams that used Garchomp (and that's the only reason that their teams were labeled as Ubers) and I never had problems taking Garchomp down. That's what I am saying. Garchomp benefits sun teams that now have a member that doesn't compound their weakness to Stealth Rock and Water attacks. Sun teams tend to have a lot of checks to Mamoswine and Weavile. Thick Fat is negated by the sun wich means that Mamoswine's neutrality to Fire turns in a weakness. I can see Garchomp becoming a staple on many sun teams - I've always wanted to use a Dragon-type on my sun team but all Dragons either had a weakness to Stealth Rock or had secondary STABs that overlaped with something on my team. Garchomp has neither of these problems. The only problem is that Garchomp is forced to use Fire Blast off a base 80 Special Attack, or use Fire Fang, while despite being physical, is innacurate and weak. Not that you are forced to use a Fire-type attack on him, but I can see no reason why you would not if you can now 2HKO Specially Defensive Skarmory (and maybe physically defensive ones with sufficient Swords Dance boosts) and OHKO Ferrothorn. I tried to use Garchomp on my sand team, and then I realized that it's much better to use him on sun. Despite Garchomp not being weak to sandstorm damage and not compounding weakness, Garchomp doesn't do anything that Landorus can't already do.
