dodging penalties being removed when you have gained a free dodge credit, is different from removing dodge penalties all together. a system requiring X wins to gain a dodge is fine. your entire premise is that
"you cant punish people that force you to dodge via trolling picks", of course you currently cant. you wouldnt be able to.
this suggestion doesnt affect that.
this suggestion slightly increases queue times, likely by 30 seconds maybe 1 minute or 2 [in extreme circumstances where a high percentage of players are simultaneously using their earned dodge credit]
and you sir, as a player who never dodges - should really look into tactical dodges. losing 3lp and 5 minutes of your time to avoid a troll or a terrible team comp. [lose 15-20 LP and 20+ minutes] example:
team a: riven, lee sin, talon, sivir, nami against team b: shen, maokai, syndra, cait, janna. if youre on team A, youre not in your promos, you arent gonna receive more than 5 minute queue timer, and you dont dodge; you have issues.
team A can only win this game against incompetence.
maybe team A can win lane; but in reality team B just has to not die and stay somewhat relevant in cs to win.
thats a dodge right there.
team A really has the option of snowballing, or incompetence on the enemy team.
------ unfortunately you cannot control what your allies pick. and more often than not, asking others to not choose their hovered champion seems to result in toxicity, or the common "can you play X" - "sure", turns into a 1st/2nd time maokai jungle. because he's op so lets say sure and do it despite having no experience on the champion.
my proposal simple offers a way to tactfully dodge without penalty, at the expense of what is likely no more than 30 seconds of extra queue time. [assuming the dodge charges once used, place you back into queue, rather than to the main menu of the client]
