A few things to think about guys.
Will take about 6 months to get to 83 , in that time just work on learning new methods of healing and fighting. The game will just require you to change your attitude and aproach on how a sin is played. A good geared lvl 83 sin is still going be a nasty. Personally I think people will use MH to top up on top of a hp pot to give a gain that way.
Also HP build rouges like myself will more than likely go towards a more ap based build as there is no real gain from having the extra manner.
It is going to make things intresting and if people quit over this then it is a clear sighn too many skilless fucks have been playing this char for too long.
It may even be the start of rouges sliding in cz, now that would be a sight.
