I saw a lot of complains in this forum that bases are not being defended due to unclear benefits of doing so. I agree with that but I found a cheap way to make people defend the base.
1. Upgrade your Flash bike to Scout radar 75 or 100 meters
2. When at the base always spawn Flash and drive around the base looking for maximum amount of enemies found by the radar
3. Park the Flash where it wont be destroyed by enemy and go fighting
The trick here that defenders suddenly see minimap full of red splashes and know where they can farm maximum kills and they will rush there to farm kills.
This way yesterday I manage to attract base defenders to elliminate enemies swarms of around 100+ people that otherwise are not visible to the defenders on the radar.
Easy and very cheap way. The only problem is that you yourself do not get any points for doing so except that you know where to grind kills
I hope more people will do that because I was ALONE doing that yesterday. At least on the bases I was defending.
