Ok thanks, just making sure.
I tried a fun build with Jayce yesterday on PBE : Mercury/Tabis, BC, Manamune (muramana), BT, Sword of the Divine, and Frozen Fist.
It's fun as hell, you do your W in Cannon form : max attack speed, then you do sword of the divine all that with Muramana toggled, it does like 800 damage a shot.
You heal like crazy because of BT, you can poke all day and when you attack someone you freeze them.
Also Manamune fills pretty fast because you can just switch stances all day and it costs no mana.
