Nope you are wrong - Tank buster is MIl-35 and next will be AH64 longbow.
Secondly Mi-17 is not attack chopper its A Medium Lift Chopper , it does not have any EW suite , no countermeasures , no RWR , no MAWS , so it got shot down
LCH is created to work in dense EW environment, with extreme Manuverability
With latest EW suite from SAAB and ISRAEL
RWR+MAWS also from Sweden ,
New Fuselage design with airframe shapings to give minimum IR emissions and descent LO.
Just to give advantage from SAM's and hand fired Stinger missile.
And it can also fill role of CAS,COIN operation which you are doubting
Also Chetak is a utility helicoptor required for evacuation from high altitude bcoz Troops have to be rotated every 4 weeks since they have danger of devloping Lung edema and failure. Its not armed if you think so.
HAL is also designing LUH for that utility only and replace Chetak.
I say this bcoz i am in Indian Army - look my profile and i have experience of Chetak and Mi17

If you want a good discussion keep it Technical . This is how mature forum discussion work
compare on -systems ,weapons and specs rather than self assuming things
