Don't forget to take back your 1H+shield after you used your bonus action. +2AC during your ennemie's turns is not that bad....
But...legal exploits are "fun" guys! If you don't like it, don't use it!
Interesting, for you fun seems to be entering the inventory every few seconds to change equipment.
For me this gets annoying fast. Thats why I try to avoid it.
