Some QoL changes for the mode

So, I got to play a full THREE games earlier in the morning before the servers probably actually caught on fire. And from that and discussion with others here's a list-- which we can add to-- of changes that would make the game better:

• Set a fixed number of drops from mob rounds.
• This would make leads less drastic and overall improve the early game. Though, in conjunction with that they would need to slightly reduce the time between picks in the Draft round, so the last pick isn't at too much of a disadvantage.
• Allow us to combine items on the sideline.
• That is, without having to buy a unit. Even just giving it a 1g cost so you don't have to spend the time buying the 1g unit would be nice.
• Maybe allow us to remove items from units without selling them.
• This one might be too good, 'cause part of the Draft round is making the choice between that BF on Leona or having the Leona, but could be nice.
• An origin bonus that grants complete immunity to a damage type shouldn't exist, even if it only effects two units.

Feel free to add things in the comments, and I'll add them to the list.
