Yeah i noticed they get reqs a lot faster than the defenders. Had a game where we were still lvl 2 and they were 4 or 5 as they pushed us to the core
Never noticed that myself. If anything a good defender is going to rack up kills and points faster than the attackers if they're being lemmings charging for the objective.
Having played the Noctus assault map a couple of times I really appreciate how different it is from the other maps. In particular the extra cover and distance from the second objective to the core, as well as the ramp up to the core entrance, really make the fight for the final objective a lot different, and the open space makes vehicles more useful as well as more exposed.
