I agree. As a neutral viewer, I find Kishwar prioritises her antagonism towards Mandana over her own game. As a seemingly intelligent player (minus her dumb moment re the recent ticket to finale), I refuse to believe Kishwar hasn't figured out by now, that if she wants to evade Mandana, she needs to ignore her - in particular, ensure that over 90% of her issues are NOT with Mandana. 
As annoying as it may be, the episodes are Mandana and Rochelle centric for a reason - this week alone, every issue that anyone had was with one of these two! Priya's issues were only with them, Kishwer went personal with Mandana during the Anger Task, and then inserted herself into a talk between the Captain and Mandana. Her arguments with Prince this week were flashes in a pan - they were back to discussing their bhai-behen equation the following day. 
Kishwer needs to move beyond her hatred for Mandana, and focus on her own game. She is a strong contender and I, for one, would definitely like to see her play outside her 'I hate Mandana' mode. Unless, of course, she believes that it's best for her game to continue feeding her stand-off against Mandana; that's a different story all together. 
As for the whole 'Mandana and target' thing - the minute Salman asked why Mandana is targeted, these silly housemates were falling over themselves, trying to prove that she is playing the victim card, and not realising they were all talking against her at the same time and thereby proving the point! Mandana definitely needs to be called out by the housemates on her mistakes; but they mess up by ONLY calling her out, and letting others fly under the radar for equally crappy behaviour.
