Which unique synergies would be OP if the recipients were reversed?
An example would be the Hulk - Void synergy. The synergy gives Void up to 3 fury buffs lasting 8 seconds each as he holds his heavy. Giving this to the Hulk would allow him to gain up to 3 fury buffs, potentially resulting in a ludicrous 3+ second stun depending on other factors (ie. Heimdall/Hela, being at low health, masteries, etc)
