I'd like to summarize some important points about Genesect, the premier U-Turner of the OU environment. * Base 99 Spe may seem not enough at a first glance, but we have to keep in mind that this is more than enough to have a fast U-Turn towards stall/semi-stall teams and a slow U-Turn towards HO ones. Towards HO teams it has even Extremespeed and/or a bulk good enough to tank a hit and retaliate. * It has a good actual bulk (even with a detrimental nature) taking in account the many resistances and only one 4x weakness, which is easily exploitable (HP Fire mainly as a random coverage). I'd like to underline that it is neutral or resistant to every form of priority move. * Download boost. This ability is a guaranteed +1 on one side of the spectrum and with an Expert Belt/LO/CBand/CSpecs the damage output really goes out of control. You can't always know if you'll have the right boost, but the fact you can switch in&out repeatedly throughout a match is really troublesome if you can't stop this Steel/Bug in time. It is too much consistent. Keep in mind that most EV spreads around are thought specifically to not boost Genesect's Extremespeed or U-turn: this means that a boost on the right side of the spectrum is what this thing need to punch holes into your team. * It has a deep movepool, both physical and special with plenty of items usable. Expert Belt itself, while often considered a poor choice, is good here to bluff a Choice item. All these points to say that this bug is really unpredictable and risks to overload its "checks" before being scouted. There is little counterplay possible. There is literally no reason to avoid running Genesect, because it is a low risk-very high reward pokemon at the point it is overcentralizing. This monster isn't Aegislash-level, but still too much for OU. Ban it.
