Sorry, mutt, not true.
Improved climb is a MTOW Enhanching procedure.
Normal take-off charts are calculted using a "Standard" V2 os 1.2Vs. Improved Climb is a seperate set of charts allowing a longer takeoff roll to achieve a higher v2, and thus a better climb gradient- but it is not specifically related to windshear.
With the advent on computer based OPTs, EVERY takeoff is "Improved climb".
Increased Vr is a suplementary procedure specifically related to windshear mitigation, and you do NOT increase the V2 as part of it.
And Micro- I agree with you! If I were suspicious enough of Windshear to use an increased Vr, I'd probably decide to wait the conditions out instead.
