Oh, it's not about patience :)
I've been waiting for monthes, of course... but I'm used to waiting, and won't cry about delays while my only contributions atm are forum posts, and a few wiki edits.
I still think that delaying the (full community) feedbacks isn't the best choice, but on the other hand, I could do the same if I was Kornel... and know what it is, not to want to release something unfinished.
The reason why I think it's bad, tough, is that I see so much discussions about imbalance... of weapons / assemblies / masteries... I think the more feedback come, the best the game will be (creating Tac boots every game pisses me off so much... I'd like to craft something else.. boots with activable haste / jumping / resistance / whatever... but just have some more options !)
I personally still have a few pages of feedback I started to wrote when I discovered the game, waiting for the 0.9.9.7 to be updated, then posted :p
Initially, it was supposed to be a "feedback mail" because I liked the game, but I got so many improvement suggestions... it kinda overgrown.
Anyway, I guess the major problem is that Kornel just doesn't have enough time (and I also got to consider doomRL isn't his only work, indeed).
