I don't understand why Chicken says the addition of shotgun helps notchers more than everyone else, is there any evidence to support that? If anything, as a BnG player who doesn't notch very often, I find that the shotgun allows me to employ exactly the sort of oldie tactics he mentions we should be allowed to resort to, i.e. borderline darksiding, uncommon shots (banks, double banks, bunny hops), quirky shots (glorious down and up bounces), constructing and maintaining hides difficult to hit for a notcher (think overhangs where either a low angle shot or digging is required to get to you, hides that are between full power notches from where they are)...
Unlimited teleport on the other hand means that when I see my notching opponent teleport into an evil hide or construct their own perfect one where they only have a single shot at me, I can simply move away without worrying about running out of teleport, then continue taking shots at them while they waste even more turns adapting their hide to be able to hit me in my new position, in turn making themselves even easier to hit.
Clearly the vast majority of the blame for the current situation where new BnG players are being pigeonholed into this one style of play falls on those ridiculous flat maps with zero height difference. On top of that, many of the highly ranked/respected players are actually using saved, identical or almost identical maps whenever they're the ones hosting, and as we've seen recently, some of them are outright breaking TUS rules on visual aids. Before proper judgement can be made on just what the effect of shotgun being added to the scheme is, surely these no doubt greater factors need to be addressed, no?
