I liked the Test, but I mainly stuck with Pilot v. Pilot. The bounty gametype was decent, but the Titans didn't do much for me. Luckily I'm a team deathmatch dude through and through, I get that it's not the most interesting gametype but I've always liked it because of it's simplicity. I found it to be pretty awesome here and I think the maps/mobility are fine. I played the first Titanfall and liked it a lot, but honestly I think 2 is going to edge it out in the end. I think they have enough time to fix a lot of people's issues, and I believe people need to wait it out and see what the final game brings.
It seems the weapons are going to be way better/varied, and I like their "perk" system, I just hope there are enough options to keep it interesting. I never liked burn cards from the first game, it felt like a chore and didn't make me feel like I was "customizing" myself, more just choosing random (mostly) uninteresting temporary advantages.
Stim is awesome, Holo is fun, the grapple is near game changing. The gameplay itself is more fun to me, the duck/slide is way better than the first and helps supplement crazy chains of acrobatically attacking/evading. I realize there aren't as many walls to jump on in these maps and I understand that concern, but I think T2 just has more variation in that regard. There are some more open areas, some tight areas, and kind of everything in between.
Excuse me for the suggested foresight, but I think people are going to warm up to this game.
Kill times though...definitely too low, Respawn.
