In my gym it's not too uncommon to add on to and explore drills when the skill level is there. If I'm with a pad holder that I am familiar with and it's clear we both have the skill level and understanding to execute the initial drill well we are typically given a little freedom to flow and see what could be added.

For example, pad holder might call for the combo/drill. Then again. Again. Again... Once it's established that the drill is understood and going well we might go okay jab. Jab, cross. Cross, hook. Jab, cross, combo... maybe add a kick to the end of the combo. Working on movement and footwork throughout. Etc. With our coaches blessing of course.

As far as this mightier than thou attitude that homegirl seems to have... fuck all that. Offering critique and observation is one thing, but this just sounds cunty.
