If you are trying to arm/disarm a C4 and a teammate is incapped nearby it will try and do help up rather than the objective. I feel that this should be the other way round or have a separate key for help up (currently it seems to be quicker to disarm the C4 as a non-engy than help up an engy and get them to disarm it + you will invariably die trying the help up around an objective).
Help up > Objective

Help up = 5 seconds
Engie disarm = 5 seconds
Non-engie disarm = 10 seconds
So yes, it is (marginally) faster to disarm yourself than for an engie to do it.

I’ve experienced this. The player should be given separate keys to press so they can chose what to do.
