You do need to keep in mind the drawbacks this move has before attempting to suggest any kind of nerf to it. It doesn't seem like you've taken those into consideration when crying for a nerf.

First drawback is that you can't use this skill after you've used a movement skill. So, apart from a few certain ways of moving, it's a choice between using this move, or getting close and hitting a crit, to give yourself another move. That would likely cover the damage Eclair provides. It's also subject to evasion, unlike those basic hit moves.

Second Drawback is that using it turns you to face away from when you fired it. This can be a major thing if you use Eclair last, since it'll give people an avenue to strike you from the back, which means your riposte, eviter, and flottlement from duelist won't proc. This leaves you open to attacks that you can't retaliate as easily against. If you also take into account Cobra, for the people who also use DH, that becomes of little use, too, as they can just attack you from the back easily. Essentially, using Eclair last leaves you more open.

It could, however, possibly do with a cooldown, or with being 4M instead of 3M. It is a problem when it can be spammed, but removing any spam ability for it will make it fall way more in line balance wise.

In summary, I believe there needs to be no scaling change. Just some measure in place that means you can't double-use the move for some big damage. There is also the change suggested by Spo, which will also reduce that damage further. But all in all? Facing off against someone using this move? I faired just as well as I would against any duelist. There are way more damaging moves that can be spammed out there.

Way I see it, too, 40-50 scaled RES/DEF is average in a tank. So I wouldn't call the tanks you tested on all that tanky, which might explain why it hurts them so much more.
