Both teams have lost 3 players. So, there's a Jarvan directly close to the turret as well as a Maokai. Xerath has the ability to clear the waves entirely so that minions can push to the turret unlike J4 and Maokai. Do you still attack the turret or do you stay a fixed distance from J4 and Maokai? EDIT: Inner turret at midlane (before Inhibitor Turret).
I guess that would depend on how much health I have and how much they have. Most likely I would keep my distance from them unless I thought we could win 2v2. Also which turret is it? If it's an outer turret top lane or bot lane it probably wouldn't be worth dying for, and if it's a nexus turret then that means there's enough pressure on their base that I would take a different turret that they aren't defending assuming there is a big minion wave at one of their other turrets.
Also what is with the downvote. I was asking a question.
Since there are too many variables you did not list, I will sum up your entire goal as ashe or any other adc- do what it takes to stay alive while doing the most damage. J4 can eq ult and flash. Maokai can root and flash. I'm assuming if you get caught by any cc you are dead. Since both of them are melee, they will use spells to clear minion waves that reach the tower. At that moment they do, if they don't have flash they won't be able to cc lock you, and you can throw 1-2 autos per wave at the tower
Stay back and clear waves, attack the turret as you can when your minions are there to tank for you. Jarvan and Moakai can lock you down for quite a while and if you're caught taking turret aggro then you're as good as dead.
