I wish there was a way that you could reset your lvl points and $ before the minions have spawned. All of us have done it...you accidentally buy the wrong item or level up the wrong ability. I think if you're in the pool before minions spawn, you should be able to reset your level points and/or sell everything back for the full price. ONLY BEFORE MINIONS SPAWN.

Or, since you have 1:30 before they spawn, simply take your time with your purchases and skill point distributon.

Happens alot, actually - just never in that first minute and a half, because I have all the time I need to do things right. The misclicks occur later, when I'm trying to do quite alot of things at once and have very limited time to react.

Essentially, my point is that a system to mitigate misclicks is all but useless in the time frame you've specified.

I dunno about skill points, it seems too special case to only do it for the first part of the game and we wouldn't want to do it for the whole game.

For items though, I am in favor of allowing players to undo purchases/sales/combines that they make by mistake throughout the game if we can cover off the abuse cases.

Accidentally bought boots instead of regrowth on Mundo...

Simply allow players to sell an item at its full cost provided that:

If it is before 1:30 and the player has not been hit by an enemy champion or turret, hit anything with an ability/attack, or used a summoner spell.

After 1:30, items can be sold at full price provided the player has not left the base (inhibitor turrets), and have not been hit by an enemy champion or turret, hit anything with an ability/attack, or used a summoner spell.

"Hit by an enemy champion," clause does not apply if you have not left the base pad. You just know some poor sap would get hit by ezreal as they miss-clicked.

EDIT: I guess I didn't make this 100% clear: The no combat clause is only since buying the item. You can refund items any time during the game, but after 1:30, you can't leave your base before doing so. Also, another abuse to be prevented: You may not refund an item if you've used its active ability.

Refunded items are broken down into what they were previously, if it was a combination item.

Refunding items also causes the player to lose any gold generated by them (philosopher's stone).

That should solve all the issues without allowing any abuse. It would be very hard to walk past your inhib turret before realizing you messed up.
