did some testing and number crunching about leech life vs superpower
>leech life deals about 4% less damage than superpower at base strength, but overtakes it in damage at 4 stacks of muscle and deals about 4% more damage than superpower at full stacks. at level 11, superpower's cooldown is much faster but leech life deals anywhere between 5% and 15% more damage depending on your stacks
>superpower gives you a shield equal to 8% of max health + 1.5% max hp per muscle stack that lasts for about 1.5 seconds. the slam moves them and works as a .5s stun
>leeech life stuns the enemy for anywhere between a second to about 1.75s at full stacks
>a no-stack leech life provides about 26% more value than a no-stack superpower at level 5, 53% more value at level 11, and 66% more value at level 15.
>a full-stack leech life provides about 38% more value than a full-stack superpower at level 5, 83% more at level 11, and about double value at level 15.
NOTE: this assumes completely base stats, and that you get the most out of each leech life. also i mightve fucked up a few numbers trying to process all of this
all things considered, id say these moves are about equal in strength.
