Scripted fights.

[Miiu]

Well than another group would complain that the fights are becoming too easy if you give people more time to avoid the attacks. I don't think you can make everyone happy in this case. I'm all for randomized patterns + quick reaction time. Because I don't really have any lag issues except the ones that occur because I'm nowhere near the server. (playing from the EU)
But I'm not going around demanding harder fights as long as there are people who have those problems.
