Auroras, like most units, are more or less effective based on terrain and micro. This is indisputable. However, some high level players think that they are overpowered in 3605, due to the speed increase they relieved. This is most apparent on maps such as Theta passage, where they can kite other T1 forces consistently.
For reference, Aurora range is 26, speed is 3.1. PD range is 26. Mantis range is 18 and speed is 3.6. Auroras have highest DPS of all T1 tanks (tied with mantis), lowest cost (tied with thaam/mantis) and have a very, very high range. The only weakness is health, which is low at 140, against 270 mantis, 280 thaam and 300 striker.
The question is what to change. Being a tank, it's balance is very fragile. My vote would be to reduce the range by 2, increase the hell by 20, for a range/health of 24 and 160, against the mantis 18 and 270. Kiting becomes less of a problem and it's a little tougher.
A second option is to reduce speed and turn rate. A small speed nerf from 3.1 to 3.0 and a reduction in turn rate from 90 to 70 should make them a little more difficult to kite with.
