On one hand pyro with detonator/scorch shot sucked balls anyway but imo they are stupid weapons for 6s. Could be because I play demo tho. Just find it annoying that there is le funny class that counters me at close range in fights and in stalemates can remove sticks off point / choke and walk through, as well as make sure no one ever has a proper buff just because they aren't hiding behind cover. Obviously it's easy to say that in a forum post in magical theorycraft christmas land but ye.
EDIT: Strongly agree with Gaz about losing to pyro tho. I can't fathom how you can lose to current pyro with shit flames in a way where you wouldn't have lost to that team playing standard 6s anyway. Last time I lost to it was when it was OP in the months after jungle inferno (funnily enough against gaz). I can't recall losing to perma pyro outside of those few months, and even there it didn't happen often.
