Kindred's Passive on Alternate Maps

With all the other maps being tuned for games shorter than 45 minutes and having less or no jungle monsters, it's much harder to stack their passive and nearly impossible to make full stacks in, say, a 20 minute game on the Crystal Scar.

already got this treatment on the Crystal Scar with his passive receiving two stacks per one soul collected. This would be a simple change that would make Kindred more accessible on these alternate maps. Other suggestions I have would be reducing/removing the cooldown to mark new champions, allowing Lamb to mark one champ of your choice while Wolf marks another random champ, or giving them a free stack every 3-5 minutes. The idea is to strike a balance between, "I'm apprehensive about picking a stacking champ on this map/I want to reroll this champ in ARAM" and, "ZOMG Kindred just became a late game hypercarry at 10 minutes!"

Other champions who could benefit from this kind of change to stacking passives:
