When I was at rank 1, a few more stars away from Legend, HECK, I roped every single turn. Why? So my opponent is unable to read me. Play fast = a single choice/ a single choice of cards. Play slow = multiple same mana cost.
For example, if someone takes the whole turn to choose between 2 cards then he finally summons one, any veteran or anyone skilled would know that the other card that wasn't played would be the same mana cost or lesser.
Hearthstone is basically like poker, OP's penalties for roping and emotes are not warrented IMO
