I support this, the buttons are to close. You can hire an ally by mistake and lose billion or trillion of dollars. Change the set up would be a big help.
When I accidentally click "hire" on an ally, I am able to just keep pressing on my screen (never lifting my finger) and slide my finger over to a new, non hiring section of the screen. Problem solved. I have never accidentally hired an ally.
Support. I have accidentally hired quite a few expensive allies because I like sporadically clicking KAW when I lose my wars.
Can always change it to confirm purchase if ally is over 30b. The hardest volleying is from 10k to 30b gold anyways. That way new players can still get the quick volley that the need and everyone else he the community won't be accidentally hiring allies anymore.
Thats exactly why something should change. Its a good, simple idea to eliminate a feature that annoys people.
No support. I've brought lots of allies by accident. It only cheers me up when others do the same. Run your finger down the left of the screen when searching. Also build a alt to take your junk allies.
