While I do believe the gamer can give opinions about games to improve them, as they are the customers, they should have a little input (might you, little, not 'what they say is law') I also think that this attack was uncalled for, criticism is saying things like 'I would rather not have skippable battles, as it would do X and Y' and give them your opinion, while another very differentthing is to insult the person.

Be polite, and you shall be treated as such, no one is going to look at you as anything other than a jerk and idiot if you only speak insults and petty excuses for said attitude.
