Why is options trading in India so pathetic ?

Ok I have treated on thinkorswim and tastyworks . Two of very popular platforms in US . Let me list downside of Dhan against those two platforms . 1. Multiple leg trade doesn't execute at the same time in dhan . So if I am trying to sell an iron condor with a certain credit I have to make sure and check if individual legs are executed . Where in TW/TOS the whole trade executed if all legs are being able to execute with our net credit requirement .. 2. no rolling ..TW/TOS provide straight up choices for rolling by strike or expiry . None of that Dhan . Have to do it bloody manually ... Am I missing any thing here ? And are other brokers same ? Am I not seeing the features I was expecting there ?
