1) Seems like you're mistaking "discipline" for "stamina". Stamina is not being fatigued by longer rounds for top cuts. As someone prone to "twitting out", it really is a matter of self-discipline, of not dwelling on that which you cannot control. Indeed if you are running a faster deck you just need to take advantage of the down time; if a game ends significantly ahead of another, enjoy the chance to relax, to run over strategy, etc. Frankly, I expect champions to have such discipline.
2) We are also talking about top cuts, not the full event, and possibly even only for the highest level events. This makes my first point even more critical; yes if it is something like Top 64 at Worlds this would be a substantial increase in time for someone to wait, but there I'd find it even more required. At a smaller event with a Top 8? Another 30 minutes per round (for 90+3, which is largely considered infeasible) isn't much, even if you make it to finals that's just an extra hour (the last round is over when you win or lose, so no waiting! :lol
, and if we switched to 75+3, that is only an extra 15 per round, which would only total an extra 30 minutes of waiting for speedsters.
3) Playing a fast deck doesn't guarantee a fast round; even if both players are using "fast" decks, the cards will fall where they may. Otherwise fast decks may be jockeying for position and forced to a crawl due to key match-ups, including mirrors.
3) I reject the premise that we should penalize slower decks (and in this case "average") decks in favor of pampering "fast decks". What is more fair and demonstrative of greater skill: giving time for a slower strategy to mature and push for a win from behind and easily giving enough time for two full games to complete even for two average decks... or keeping rounds as is so that speedy decks/players who lack self-discipline won't freak out while waiting?
I know some players have more legitimate reasons for the wait being an issue, but let those be addressed. I personally have issues with my g.i. tract that can mean I either need extra time between rounds, or would be better off if we could rush, rush, rush before anything has time to go wrong... but no tournament should
have to adjust for me, even if it is as small as possible with only seven other players.
