I've got a good one, Riot should really try this one.
Abilities : Mana and Energy costs are removed; Blood Well, Fury and Flow generation doubled from all sources; and Health costs are reduced by 50%.
Cooldown reduction : Automatically set at 80% for abilities, activated items, and summoner spells.
Abilities with static cooldowns, such as Sweeping Blade, Missile Barrage, Dragon's Descent and the global cooldown on Udyr's abilities, will not benefit from the 80% cooldown reduction bonus.
The only exception to this are the revive passives of Aatrox, Anivia and Zac, which are set to a 60 seconds cooldown.
Attack speed: Bonus attack speed is doubled ( × 1.5 for melee champions).
Movement speed : +60 for all champions
Tenacity: +25% for all champions
Critical strike damage : +25% for all champions.
Gold income: × 5 gain for all champions
Also,
This unit does tons of damage.
No poros were harmed in the making of this game mode.
Tons Of Damage!
All health pools and damage dealt are multiplied by 1000. In the HUD this will be shortened to K form.
The death recap will show damage taken as TONS (X%), where X is the percentage of your maximum health taken.
Removed Level Cap
Champions will continue to level-up beyond level 18.
Level cap is now 30.
The amount of experience required to level up continues to increase at the same rate.
A champion's base stats will continue to increase at the same rate, but no other scaling is affected.
No additional skill points are awarded.
Heal Embargo
In order to overcome the lustful thirst of blood greedy players, healing is tuned down from the beginning, but scales up to be nullified as the game progresses.
All direct healing effects are 50% effective at the beginning of the game, increasing by 1% every 30 second, up to 100% effective at 25 minutes.
Shield Overload
In order to make more just at the eye of our Lord Urf, shields are tuned down to compensate the now spammable spell to which they belong.
Non-ultimate shield scaling ratios reduced by 50% (Except Diana and Udyr, just because).
Smite
Charge rate reduced to 30 seconds from 75 seconds.
Cooldown between charges reduced to 10 seconds from 15 seconds.
I don't think Riot has done anything like this in a long time, and it would really be a fun addition to the RQGM!
The best part, you get to pick your champion, too!
