The 26-year-old Scotland international - who made three appearances in last year's Six Nations, scoring one try - has made an impressive start to this season.
The Warriors, too, have been starring in the GUINNESS PRO12 having won all four of their games ahead of Sunday's clash against Treviso.
And Seymour, who joined the Warriors from Ulster in 2011, says Gregor Townsend's troops have built a winning mentality that is benefitting his own game.
He told the Scotsman: "I want to score tries, it's what I'm employed to do but, if the other guys are getting bags full of tries and it puts us in strong positions where we're playing more games and I'm getting more opportunities to play because they're scoring, I'll take it, but rivalry's a good thing, is it not?
"It's a really, really good unit to be a part of. We are in a position where we are confident in each other, know what each other is thinking, and that works for people coming in and out.
"We have a strong squad. The wingers may change one week, or the centres may change, but we are still familiar with every No.10 and every combination.
"It is a complete blessing. We get a lot of ball, great service, and the offloading ability the forwards have now is incredible.
"The last couple of years have been phenomenal in regards to the type of rugby I have been involved in."
