As much as I hate Moray Towers, banning it I don't think would be the correct decision. You have to remember that while the map may be heavily in favour of E-liters, there are things which you can do to stop them, like using Killer Wail and Inkstrike. They may not secure a kill because they can be evaded, but it does temporarily stop your team from being fired upon, during which you can make a push and neutralize the chargers.
I also see an issue with banning maps because they're too good on it. You're essentially saying "I don't like this weapon, let's take away the maps where they excel". This is not the right approach and it's completely asinine. If you're going to do that you might as well ban the weapon the itself.
