Rotating the strike needs 360 shot making ability with timing and placement, which clearly missing - it's a top hand job. But, to the support of PAK batsmen, they are groomed either on these dead slow wicket, where you need bottom to play shots, on even worse domestic wickets where you need luck as well to connect.
I think, Dean Jones (one of the best ever in rotating strike), once explained - taking singles are like net practice - you have 5 holes (gaps) and what you need is to adjust your body balance & footwork to get into position and guide almost every ball into one of those holes, on either feet using your wrists. Unless ball is coming on to bat, it's impossible to learn rotating strike - and it's a learned skill, not genetic .... otherwise some of the best ever rotators won't have come from PAK - Javed, Asif, Zaheer, Malik (Salim), Inzi, MoYo ..... even YK is a fantastic 4th innings player because he never allowed bowlers to target him for 10-12 balls at one go on 4th-5th day tricky wicket (somehow, it didn't work for him in ODI)- and these players learned their initial game batting in 600-700 sort of innings.
Umar started career with fantastic rotator, then UAE & PAK domestic wicket made him a "cow slasher" .... now probably that slasher word is also missing from there.
