I had a lot of hope when the recent “invasion overhaul” was announced, but that turned out to be just tweaking of rewards without any redesign.
Everyone understands at this point that invasion is a grindfest. The fundamental problem is that on teams where you can one shot any boss (i.e. red and yellow), spamming quick fight causes an infinite loop where you actually get more resources than you started with. Eg if you start with 240 stamina, this converts to 25 breakers (20 breaker fights + 5 bonus at the end), which converts back into 375 stamina. That gives you loads of room for failed attacks as you have over 50% more than you need.
The result of this, along with the convenience of just hitting a quick fight button, is that invasion is incredibly easy to automate and players actually playing invasion on a mobile device have absolutely no chance to keep up with people running autohotkey scripts 24/7 on an emulator.
@Polaris - please can you consider steps to break automation in invasion. It used to be a very minor issue for a few players, but it seems pretty widespread now and with the increased rewards, matters a lot more.
