using arrows for 180
o turn around is extremaly slow while fighting. I would never turn around to escape from combat playing PS.
From other things, its unprecise, as you can never trun in the direction you want
And you can't really look up and down while doing so, coz you have not enough fingers.
The answer is on M key hehe
But there is currently no feature, which would make it possible.
As about running backwards, you do it in real, but you can't run as fast as forward.
As about instant turning around, it is also possible and i suppose there will be proper animation once.
And what they did in that MMO was rather stupid solution, made it made it fun in some way, but creating unrealistic boundaries at the same time, which don't exist in real
