If you look at the Temp Bans, on week 43 (24/10-30/10) Hawk is on both the Perma ban list and the Temp ban list.
I see this as either an Error, or certain Permabanned cards may become free very shortly.
They wouldnt let such a broken card back into ELO.Not with copper still alive.I wouldnt get my hopes up,and trust me,i love using Hawk and it would be a surprise of epic proportions if he did,especially seeing how the bans are decimating such powerhouses as "Lea" and "Arno".Its a screw-up,but i wont say i told you so.
This doesn't necessarily mean that Hawk will be the only card being removed from the perma-ban list (if this is indeed what is happening); he could just be the only one that is starting off on staff-ban. Also if there is a new bout of ban-swapping than I would assume that they will be adding some others to the perma-ban list also. *cough* Toro *cough*
I guarantee this was not a mistake. With the new format of bans, they can start to play around with cards and see what impact they will or won't have on the enviornment and they can quickly switch it back. I think their goal is to have it so every clan is viable in ELO and they are just seeing what they have to add or subtract to balance this. Look at GHEIST, they just banned Toro and Rolph and there was still a ton of GHEIST decks, they added Leviaton and Bristone to the mix and still a ton, they take out Methane too and now there is hardly any GHEIST, so they will start to tweak. Is Hawk a mistake, nope.
