I have seen this in my games. It might not have worked out well for them, either. I've also seen Katarina jungle. Don't do that.akali can jungle
I thought the tooltip for Zyra said the second plant did 50% damage -- I didn't realize it was 75%. (or maybe that's scaling from level 5 W, and I usually kept it at level 1)
I also won a Zyra vs Zyra lane. It probably helped that the other Zyra tended to disconnect from the game every other time they got hit by a snare, or half the time they didn't get hit by a snare, however.
If you have enough time to farm and purchase 3 bloodthirsters, let alone farm all 3 of them without dying, let alone two phantom dancers as well, you probably could win even without doing that. Why not get one IE instead of one of the BT's? Your crits would do more.Stacking 3 BT 2 PD and 1 Berserker's greaves. Works on almost every champ. lol.
