I think most people would not mind paying their hard earn cash for entertainment – be it paying to have a chance to play to win or simply just pay to win.
What people do not like is to be paired against ‘talented’ players who have achieved all plants at maximum level and or with 0 sun cost.
I enjoy winning from using my PVZ knowledge and skill but not by luck, I have above average level plants because I have been a PVZ player for quite a long time and when Battlez paired me against low level plant players, it makes the winning meaningless. Likewise, I do not mind losing to real game players with better game knowledge and skills as this gives me a chance to learn and make progress.
Now since I know some Battlez can start with handicaps such as no sun requirements on maxed out plants, we normal players or payers would not stand a chance… Now this is discouraging.
