Do dodge penalties jump too severely?

Last time on...A smurf getting smashed by Silvers... 1st champ select: A yasuo that never played the champion instalocks bottom because he's "so tired of autofill" even though I said I'd give him top. Jungler locks in veigar with cleanse /heal "If he's trolling im trolling" Well it's whatever I can dodge a game I guess, goodbye time and lp. I wait until the very last second, just in case, and have to dodge. 4 Minute Dodge Penalty. That's fine. Fast forward and... 2nd champ select: I'm met with a varus jungle who proudly proclaims: "Get back in the fields you cotton negs!!" So I decided to check out his op.gg and...he is inting every game. 0/16, 0/12, 1/31, 0/7, all the while buying random item components. Our mid locks in twitch and our support, lee sin. - XxSgtDi*kHeadxX - 0/14 - And no, that's not his real name. So I wait until the last second, and have to dodge. 30 Minute Dodge Penalty. Woah! I dont ever dodge though? I don't dodge full ad or other bad team comps, bad teammates, non-meta picks or rivens. Only trolls or inters to save lp I know I'll lose. Maybe you should think about less strict increases in punishment, in case these situations arise. 4 to 30 minutes seems crazy to me. In my opinion, I'm being punished severely enough to prevent me from playing again today (leaving town soon), for saving 3 or 4 innocent players from a horrible game and loss of lp to the hands of a flaming troll.
