Fantastic video mate, you hit most of the important points I think.
I might have explained a bit more about how the merc rotations work, this seems to catch people out, mention that the “clock” icon means it’s only temporarily unlocked or something.
You touched on it very briefly but I think you could have been a bit clearer about the different defuse speeds.
There wasn’t any mention of remembering to hand out ammo, listening for people asking for ammo, looking for ammo symbols above peoples heads, or an even more general think I notice is that new players don’t use, or forget to use their ability, if you’ve got mines or turrets remember to deploy them.
The change in destroying generators mechanic might be a good thing to add.
But as I said it was very good, these are just my thoughts on a few tweaks to make it even better.
EDIT: Oooh yea, shibbyuk makes a good point, people don’t understand how the airstrike mechanic works so it would be nice to explain that, also to remind them not to stand in an airstrike or keep pushing the EV into an airstrike.
