Two simple changes that would allow Aatrox to be easier to balance

1. Heal vs Minions is 50% and Heal vs Champions is 150%

2. Heal removes an equal amount that is healed from the Well but decay timer is increased

Number 1 Rewards him for being aggressive and trading and punishes him for just safely farming and doing nothing all laning phase. This change would allow Riot to buff his base stats and adjust other aspects of him for the better without worry of making him too broken (the current reason they don't touch him with real changes)

Number 2 allows more tradeoffs for his W, allowing them to adjust the damage, scaling and general uses of the forms accordingly
