Just had a very long game, vs a good team. Solid I would say. The map was cataclysm so I had many opportunities to shield up. I did some strikes in the end the timer expired, and i was tired so let it expire :).
In my experience, shield, shield, unkillable (those 3 perks) works good for heavy teams.
One dude was complaining about how broken supposedly wraith was. Well he apparently didnt understood green meteors do recharge, plus unkillable allows me to armor up fast, so from time to time I went and hide in the area inside dome.
First time I find this map fun, just because I was able to use it at my advantage to last.
