I think the reasoning for my original vote for Murkrow being banned still applies, though it's hard to argue that Murkrow is going to be sweeping with massive amounts of recoil. Murkrow has the ability to 2HKO almost anything just by spamming Brave Bird (Slowpoke, Frillish, etc still die) and either following up with another Brave Bird or using Heat Wave / Hidden Power Ice to finish them off. Bronzor is probably the safest switch-in solely because it's pretty uncommon for Murkrow to open with Heat Wave unless it also KOes the Pokemon currently on the field......however it can't really do anything back and actually still loses. Nothing can switch in safely and then actually kill it.
This isn't even considering Sucker Punch and how hard it is to play around considering the only Pokemon that are fast enough for Murkrow to need to use it against are Choice Scarfers....Choice Scarfers don't have the option to mess around with set up / non attacking moves. Every other Pokemon is just slower.
If you want to bring up the lack of a stable bar of HP, just think about what that means first. If Murkrow has very little HP because of Brave Bird / Life Orb, that means it successfully got a bunch of attacks off, and especially in Brave Birds case, it actually means you did a lot of damage. If the only argument against Murkrow being banworthy is "once it takes out a couple Pokemon, it's low on HP" then I don't think it's possible to have a two-sided discussion, unfortunately.
