However in the forest, Jaune has a pretty big bruise on his cheek after Cardin beats him up and if I recall, there wasn't much of a gap between Jaune hitting him with a jar and the Ursa showing up. As a result, I can't imagine their fight had been going on for more than 10 minutes, even with Cardin toying with him.

As far as Weiss, it is possible that she can divert her Aura into her Semblance, but if she has weak Aura you would assume her Semblance would be weak as well. However she is seen making multiple Glyphs all the time and was only really shown getting tired after the Nevermore fight with all the things she had to do. Another factor is that in the WoR-Dust episode, they mention Dust can be triggered with Aura. The problem with Weiss is that we don't know how her Glyphs react with Dust. Based on the last episode, we know that a Semblance can be combined with Dust from the Shadow clones. This could mean that Weiss' Glyphs take on the properties of her Dust and have no actual properties of her own. Either way she would need to use Aura to use Dust. However this would mean that by herself, Weiss has no offense or defense going by what people have been saying about her.
