FlexQ question

Would it be a total jerk off move for me to use FlexQ as my warm up/first game of the day/new champ/new role? I REALLY hate normal's, it's so hard to actually use it for practice when it's filled with off meta picks and other people trying new things, which I 100% support I'm just saying for actual practice I'd prefer a game mode that means at least a LITTLE to the other players.

Also just so I'm 100% clear, I start every day with a custom to work out the kinks in my hands, (I've been a telecom tech for 12 years and my hands cramp easy now) or whenever I am trying a new champ I practice last hitting, skills etc with customs and bots.

So I guess I'll make this a poll ~ Is using FlexQ as my 'normal' mode uncool? I'm sure my rank in flex would never go above Silver so I wouldn't really be bombing anyone at higher elos if that makes a difference.
