Manamune + Jayce
I have a question about Manamune. Now...I'm not that experienced a player...hence my question...why do people go into buying a last whisper or bloodthirster or brutilizer on Jayce after buying a tear? I don't understand why you wouldn't push the manamune first considering that it continues to stack just like tear...but also stacks based off auto attacks.
To me it seems like it would be more beneficial overall to build the manamune followed by a brutalizer and then a last whisper. Am I missing something? I guess I just can't ever figure out why everyone waits so incredibly long to upgrade tears...when what they're upgrading to continues to have the passive (if not a better passive in manamune's case) than what tear is providing. Can someone please explain thoroughly what I might be not understanding?
thank you.
