I've been playing since alpha and around 3500 mmr skill level, that being said I have been just punching in the picks and bans and then puting counter, tier, and synergy and it does seem to work pretty well actually. The suggestions aren't bad. I know the counters and good team comps, but it's nice to have some other ideas sometimes. I don't think it hurts to get its opinion. Tryer out and see what you think.
