100% Guaranteed unit spawn
TL;DR at bottom.
To help fix 100% bad luck even when you are using xp/levels properly to maximize chance of getting a unit.... and to make ranked more fair. Maybe there could be something implemented where if you spend X amount of gold, you can guarantee unit shows up.
Say you have 60 gold. You can reroll for high risk high reward for that final nidalee or kassadin or whatever. You may get it in 2 gold. You may get it in 80 gold. You may never get it the entire game (i have spent over 90 gold between lvl 6 and 7 with NO luck)
If you spend 30-40 gold, it may or may not be better for you in the longterm. It's a high risk high reward system that helps add more impactful decisions to the game as opposed to making it 100% RNG
This should only be allowed ONCE per game though, to keep the RNG spirit of the game alive without completely screwing yourself for no other reason than you got unlucky. Also, this should only be allowed for tier one and two units as they become so scarce late game and it can really screw you over. maybe 30 gold for tier 1 and 40 gold for tier 2. not sure. Nobody should get a guaranteed 4 or 5 star. thats just too much. Also, maybe putting a level restriction on it.. like 7 or 8.
You can watch every single board. Have the optimal level for rerolling, and still never see the unit in the carousel, or in rerolls. It happens.
How could we do this? Maybe highlight the unit you want somehow (you must own it first), and then hit a button that causes a special reroll that costs a lot with the unit you want and four other units.
One last point - Maybe make this only a ranked feature so people can enjoy the goofy stupid RNG they know and love/hate in normal games.
First person to count how many times I typed RNG gets a cookie.
TL;DR Spend 30-40 gold for guaranteed tier 1-2 you own High risk high reward More influential choices to keep RNG and strategy in mind. Once per game You can only do it at a certain level (7, 8)
