Right now Ana’s nade with the long cool down timer is just a crucial ability you just hold for the right time. No matter the timer it still affects you the same just less. With a change of if the enemy gets hit they receive a reduction to the heals they get would benefit both sides since you can now give ana a smaller cool down timer
Yeah they’ve nerfed Ana again and again for the past year but she remains the best and most picked support. You just can’t balance an anti heal on cooldown in 5v5.
Making it a heal reduction would allow for Ana to get some of her power reverted in other areas (made healing 100 again, 75 dmg shots, nade cooldown shorter)
