Now in terms of being blind and disarmed then your on your own. If your foolish enough to remain in battle while blind with a weapon that can be disarmed than thats your own fault. There are ways around it.
This statement is ignorant of the fact that many classes can disarm cursed weapons.
It is super possible to get lagged, blinded, and disarmed all without being able to even enter a draw command. At no point does a single 1h weapon have any advantage over a 2her in this scenario. Monkdude kicks dirt in your eyes, lands a chakera or even back to back rounds with chakeras, dragon disarms your cursed main hander.... are you sure you want just a dagger over that polearm? Losing the automatic draw of your two hander, I don't care if you'd RATHER be in a dual wield stance, while you are blind can be fatal. At no point is a single one handed weapon the right answer.
Then perhaps something could be implemented as an "auto-draw" which can be toggled on/off. Not every battle has those worries in them. And the way doublesheath works now can either be good or harmful. Not saying a one hander is something you should fall back on, but if you arent lagged you could always double grip it if you needed a 2 hander.
