Dragons
At first i thought the infernal dragon should be changed as its superior to all dragons mainly because we think of inferal as a dragon that gives you a damage buff but what it does is increase your AP/AD which also ties in with what im going to say ... because infernal increases your ad/ap it is basically acting as an earth dragon because you get more damage to deal more damage vs turrets so i kind of felt like infernal should be change to increased damage vs minions/champions rather than a stat increase or keep infernal as it is but change earth dragon to provide resistances which can help with the abundance of damage around
After thinking about it in more detail though i feel like the whole dragon system should be changed ... i think getting random generated dragons isnt really good design ... getting dragoon should be a strategical choice rather than what dragon is next? oh its air dragon lets get it as it helps our kitable udyr close gaps more
I feel like dragons should be kept as elementals and in an order say like air water fire and earth - i see them working as a one time buff for example going by the order when killing air dragon it will drop an air dragon egg picking up the egg and then summoning it (any time summon) will summon the air dragon back which will send out winds across the map in one direction granting huge speed if they move in that direction but it could also work against them such as running into the wind slowing you - could be effective for enagages or as a disengage
Picking up a water dragon egg could summon the ocean dragon to send rain crashing down giving massive mana and health for anyone standing in its area - could be effective to help a losing team get their one chance of coming back by having a good teamfight
picking up the fire dragon egg summons the infernal dragon dragon to spew a fire breath from the sky in a lane in front of the user dealing lots of damage to all minions and champions(can be dodgesort of like the lane wide beam in nexus siege game mode) - could be a good sieging and anti siege tool
picking up the earth dragon egg summons the earth dragon to summon rocks to block off a lane - effective at helping a losing team to protect against a lane which could be effective vs super minions
These are all just ideas they dont have to provide that buff exactly .. i think an ordered dragon with a one time buff is a lot more fair with that stratgeic value is what league needs more of as opposed to rng
