It's actually pretty necessary for soloq, at least for high elo. I don't really want to wait for an hour to get into a game if i queue up in the morning and afterwards get matched with a wide range of people from challenger to d5.
You should just get used to dodging if you want to climb. People might be discouraged to dodge cause they lose LP and wonder if they could in fact win the game they dodged. In reality LP doesn't mean anything and neither do divisions if you keep your MMR in tact, which is the only thing that matters. You don't lose MMR by dodging and if you lower your chances of losing MMR your LP income will greatly increase even with the dodges.
When you get into champion select you can use OP.GG Multi to check out your teammates. If you or someone else is autofilled, first timing a champion or just has a bad win rate with a certain champion they picked you dodge.
