So I got Titanfall 2 knowing that the game has had some major changes from the first one.
I have to be 100% honest and say that I wasn't liking the multiplayer very much for these first few nights. One issue is that the perks unlocking with level put lower level characters at a big disadvantage. As an example, Map Hack was one of the best Burn Cards in the original game. You could only bring 3 cards into a match and the effect disappeared with your death (or loss of Titan). In the new version, Map Hack is a high-level ability which can be used multiple times in a game. It doesn't last long, but can be a huge advantage.
The Titans were dumbed down. Last version there were 3 chassis and you could mix and match the weapons, weapon unlocks, and a handful of abilities. Now, there are six archetypes. Each one comes with its own unique weapon, secondary weapon, defense, and special ability called core. Like pilot special abilities, the core unlocks over time with kills & goals speeding it along.
Wolfrat and I are playing mostly with our friend Nyankoframe (he signed up on TAG, but doesn't post). We were regularly getting curb stomped in Bounty Hunter (which can be a fun mode) and last night decided to do Attrition for a bit. Finally, we were able to hold our own and win some games. I think this was a combination of getting familiar with the maps and being high enough level to have some good abilities and add-ons for our weapons. Wolfrat got the sixth Titan, Legion, and was instantly in love with it - finally felt he had something powerful. I had been using Northstar with plasma railgun (simplified greatly) and then started using Tone (who totes the 40 mm cannon) - both of those I like.
So I encourage my fellow TAGgers to stick with the game long enough to unlock all the Titans and learn the maps. I look forward to gaming with you!
