That is if you can get an oppressor there. I have won matches where we lost two towers and held off the teams oppressors reaching the core. We ended up getting down their towers and had enough kamikaze dps to do more damage on their core than they did to ours. This isn't done by healer stacking. CE can also be gathered all across the middle and you can easily keep your team a float with CE plus some without holding the generator.
