Speaking in The National, Dickinson said: "There's been some really good stuff but other things have been frustrating. That's just the same as any start to the season, especially when you're drip-feeding boys back from internationals and that can be quite a challenge. We are in a pretty good spot.
"The good things that we do in one game, we sometimes don't do them in others. Our set-piece against Ospreys was a little bit messy and it wasn't as clean as it needs to be, despite scoring maul tries. Our scrum wasn't as clean either and there are a few issues we need to fix there, especially against Treviso because there's is very good. We need to tidy up around the scrum and that will be important."
Weir's playing opportunities have been limited in recent seasons, but he returned this summer in pristine shape and coach Dickinson believes he has 'massive value'.
"That's good old Dunc," said Dickinson on Weir's display on Saturday. "Duncan has massive value, he's safe as houses with the boot and he can control the game. He's vocal and experienced and that's vital for this team. He will play a big part this season and it was good to see him get back.
"He's had a couple of injuries the last few seasons but he's back in the groove and he's as fit as I've ever seen him. His motivation is extremely high and it's great to see him back performing with Glasgow.
"He's worked so hard. He was in with his kids over the summer using the gym and he's still grafting. He's taken summer really seriously and he was in working on his robustness so he can stay injury-free. I think he will play a big part this year, which is great because it gives you the option to bring on quality. He's performed big moments over the year for club and country - so he's someone you can rely on."
