From I saw in the video, MAX suits got eaten alive by ES main battle tanks and Lightning tanks, so I'm not too worried about them. Yes, they are a force to be reckoned with indoors (woe to the COD kiddies when they try to run and gun quick scope against a MAX for the first time
), but come on, all of us here know a MAX can be solved with a few boomers, an AV weapon, or just running away behind cover really fast.
What I'd be worried about is a group of MAXes backed up by good engineers and medics with their pew pew heal/repairs going crashing into a base. That's going to be some glorious ass whooping right there if you are not prepared for it. The funny thing about "OMG rush!" tactics in Planetside though is you can prepare for them, or get buried by them, as this is a massive strategy game at heart as well as an FPS.
