We don't need a heavy rework, all we need is a couple of potency buffs in my opinion.
Sure Shoha is bad. Its not THAT bad tbh. its free potency. What needs to be change with Meditate is the server ticks. It should always give you 1 stack as soon as you press it. Cause currently its just praying to the rngsus that the server tick hits when you meditate fish.

All sam really needs is potency buffs. That's all. And the change to meditate ticks ofc.
