exalt without motes is like a tank that's run out of ammunition and diesel. Technically it's still pretty durable - no need to worry the driver will be killed by guys with knives - but anything that was actually a threat to the tank while it was fully operational will have a much easier time pasting the people inside.
If I may use your own analogy. An an exalt with no Essence is essentially a battle tank that is out of main tank gun shells but still has mounted machine guns and fuel to move and possibly just bulldoze anything in front of it still.
Then again we're still talking about a tank we're just agreeing in different ways I disagree with the statement that getting an exalt down even to empty is like enough to even partially guarantee that you'll kill them because yet again it's nothing stopping anyone from retreating.
It's really that that really boils it down for me it's like no one has said anything about the fact that no one can catch Molly if she decides to run and she can just grab people that are with her because she has world class strength in her shintai form and just book it if she doesn't already have the telekinetic Grabbers active. All of the exalted also just have passive abilities that don't rely on Essence to work.
Essentially any place that she couldn't escape from would trigger cracked cell which means with 13 dice in combat fight fight it's literally free eats at that point it wouldn't be until like a creature has an analog of Black Wind / Celerity that they are likely to slip in attack past her defenses. Which still isn't even a guarantee they'll be able to hurt her either.
Molly has defenses that are completely independent of her Essence that just make her a threat to all wizards flat out because she has active counter magic that can dispel fireballs and dispel magic in general from Wizards.
If we wanted to we could literally dispel the effect someone created to peel one of our charms off us because that's how it actually works they cast in effect it tries to affect us we get to counter magic if we wanted to or we decide okay you have spent the magic of this turn trying to take down one of our defenses will take your head off with an aggravated damage sword.
The spell is cast as an effect and because it's a spell we get the opportunity to dispel it likely would get to Parry an attack. And successes on a spell roll and successes on a dispel roller counted one for one and I don't know what level of feat dispelling a charm is but you do still need a certain level of successes to actually cast certain effects.
Though I really don't know how it's to say it I disagree with your point and you have not given me anything that would budge me just like I haven't given you anything that would bud you either so we're just kind of at an impasse.
Well I get your point that mote tapping is dangerous but I think you are overstating the danger in the vast majority of situations against the vast majority of opponents or positing a situation where we go in empty without any of our long-term charms active or without our shintai active which has never happened.
unless we are going into this expecting a fight with a creature more dangerous than any deity we have fought so far we are not in any more Danger then we would be if we had 10 Motes of essence then we are at 2. Jesus this is a long winded.
