I don't remember the exact quote, but it went something like "Those mechs are really slow and like tanks, slow is boring. We want to still have agility."
After seeing some of Titanfall, the "mechs" they have in that game seriously arent even mechs to me. They're the normal, average FPS soldiers, except bigger and made of robot. They even have to manually reload their guns and all. Because, you know, it's totally logical to give a giant mech fully articulated hands JUST so that it can reload it's amazingly impractical bus-sized gun. As opposed to, you know, having guns for arms like most proper mechs do.
But yeah, that was the impression I got. That the whole thing was VERY gimmicky, and the robot combat seriously does look to me like inflated normal soldier combat, except that you're able to step on players that arent yet inflated.
Looks terrible to me. If I want mech combat, I'll play MWO, which is great. If I want FAST mech combat, I'll play Hawken, which is good but I'm horrible at. But Titanfall.... just.... no.
