Holy shit are some of you riding the slow pony to the rubber forest or what.
Gothitelle is slow, yes, but its fast enough for what it needs. Max speed Modest hits 229 speed, as fast as Adamant Scizor and faster than basically all walls. If you run Timid it can outpace defensive base 100s, Modest Politoed and Breloom. No it isn't going to be running circles around the metagame but its shitloads faster than a lot of things and its actually faster than Magnezone, and maggy gets usage.
Frail? It is not frail. Infernape is frail. Lucario is frail. 70 / 95 / 110 is not frail. Its about as tough as Latios.
You say it doesn't hit hard? This is a fair point, 95 base isn't particularly dangerous with only psychic STAB. But again, it doesn't need sweeper level offenses to do what it needs to do. Gothitelle is a trapper.

This thing is the death of modern BW 2 stall. If Gothitelle becomes popular (honestly I see no reason why this won't be OU) stall will not exist in its current form.
-Psyshock OHKOs Tentacruel, Breloom, Infernape, Terrakion, Venusaur, Keldeo, Jolteon, Amoonguss, and Conkledurr while demolishing Volcarona, Ninetales, and Thunderus in one hit after Stealth Rocks. Blissey is 2HKOed!
Thunderbolt destroys Cloyster (if Timid you usually outrun it), Gyarados, Tornadus, Starmie, and Skarmory in one hit. It also puts heavy pressure on Jellicent, Politoed and Vaporeon, 2HKOing them.
HP Fire OHKOs Scizor, Abomasnow, Forretress, and even Ferrothorn after Stealth Rocks. Gothitelle outruns all of them and survives Bullet Punch.
Energy Ball is mostly filler but can be used to OHKO Gastrodon, Rotom W, Mamoswine, Donphan, and 2HKO Hippowdon. It even has a good chance of 2HKOing offensive Tyranitar with Stealth Rocks.
... HP Ice is another option mainly to hit Gliscor but then you lose the ability to OHKO every Rapid Spinner and Spiker (barring Deoxys D) in OU.
There are also endless Pokemon that Gothitelle can not directly switch in on, but instantly die locked into the wrong move. Terrakion Close Combat, Landorus HP Ice, Latios Draco Meter, Tyrantar Superpower, Tornadus Focus Blast etc. Gothitelle has SO many chances to get a free kill and otherwise rip to shreds defensive cores. It has flaws of course but it fits perfectly with Volt Turn teams and balance / offense that has issues with stall.
Like with Chandelure it is easily picked open by Tyranitar, but that never stopped the ghost from being used in DW OU.
