Well alot of people didnt realise there was no clocks until a few days before the event as they assumed there would be clocks despite there being zero reference to clocks in any of the material, i also know that there were some players that refused to take part because multi masters werent allowed, just as there would be players that would refuse to take part if multi masters were allowed
Any information gathered after an event is likely to be skewed towards that event, but from the admittedly small sampling of a clocked event i have previously ran, there was several players that wouldnt attend clocked events in the future, and none that wouldnt attend non clocked events.
Realistically there won't be a player pack everyone is happy with, yes some people want to play on clocks, that's their preference, but the tournament organiser has made it clear that this event will not be using clocks, if players arent willing to play without clocks, or multi masters this event isnt an event that they are willing to play in.
